Tamil Jathagam Biodata Format — Free PDF
A deep dive on the jathagam / Rasi / Nakshatram block inside a Tamil thirumanam biodata — not a full biodata rewrite. Field samples, porutham context, mistakes, and free PDF templates.
TL;DR
- Jathagam fields are the first filter for many Tamil families — Rasi, Nakshatram, Lagnam, Gothram, Chevvai.
- Full page layout lives on thirumanam biodata format Tamil; this article is the astrology block zoom-in.
- Fill fields in the free biodata maker → export PDF → share on WhatsApp.

Why the jathagam block matters
In Tamil Nadu and diaspora communities, a thirumanam biodata without clear jathagam details often stalls before a meeting. Relatives forward PDFs to a family astrologer; incomplete Rasi or missing Chevvai status means another WhatsApp round-trip. This page does not replace the full Tamil thirumanam biodata guide — it zooms into the astrology strip so you can get porutham-ready on one page.

Open makerField table: essential vs optional
Pre-filling these fields lets families do a quick filter before engaging their priest. If you only send DOB without Rasi/Nakshatram, expect delays.
| Field | Importance | Example | Note |
|---|---|---|---|
| Date of Birth | Mandatory | 14 March 1996 | Use clear month names if NRI relatives read it |
| Time of Birth | Mandatory | 11:32 AM IST | Write Unknown if unsure — never invent |
| Place of Birth | Mandatory | Madurai, TN | City + state for chart casting |
| Rasi | Essential | Kanni / கன்னி | Moon sign for porutham |
| Nakshatram + Padam | Essential | Hastham, 2nd | Padam improves matching accuracy |
| Lagnam | Recommended | Simham / சிம்மம் | Ascendant — many priests ask first |
| Gothram | Essential | Bharadwaj | Avoids same-lineage alliances |
| Chevvai Dosham | Essential | Illai / Undu | Tamil Mangal Dosha — be explicit |
| Gana | Optional | Deva | Helps 10-porutham review |

Sample jathagam strip
DOB: 14 Mar 1996 · Time: 11:32 AM · Place: Coimbatore
Rasi: Kanni (கன்னி) · Nakshatram: Hastham, 2nd Padam
Lagnam: Simham · Gothram: Kashyapa · Chevvai: Illai
Girl English guide: shaadi biodata for girl · Boy: marriage biodata for boy · Photos: photo guidelines.
10-porutham context (keep it short on the PDF)
Tamil matching often uses dasa porutham (10 factors) including Dina, Gana, Mahendra, Stree Deergha, Yoni, Rasi, Rasiyathipati, Vasya, Rajju, and Vedha. Your biodata does not need to list all 10 scores — that is the priest's job. Your job is to supply accurate inputs so those scores can be computed without chasing birth time again.
- Many families look for roughly 7/10 poruthams before a meeting — local customs vary.
- Rajju and Chevvai are frequent early filters; blank fields look evasive.
- Attach a full chart PDF later if asked; keep the first share WhatsApp-friendly.
General marriage biodata framing: biodata for marriage · sample biodata · modern vs traditional.
Chevvai Dosham wording
Write one clear line. Preferred Tamil/English mix: Chevvai Dosham: Illai or Chevvai Dosham: Undu (Partial). Hiding status wastes everyone's time — charts reveal it. Traditional advice pairs Chevvai with Chevvai; modern families may weigh remedies differently, but honesty still wins.
- Chevvai Dosham: Illai
- Chevvai Dosham: Undu — open to matching with Chevvai
- Blank field or "will discuss later" on first PDF

Rasi & Nakshatram naming table (bilingual)
Western sun-sign labels confuse Tamil porutham. Always use Vedic moon Rasi and the birth Nakshatram from your family jathagam sheet. Bilingual spelling reduces WhatsApp autocorrect disasters.
| Write as | Tamil cue | Avoid |
|---|---|---|
| Mesham / மேஷம் | Aries (moon Rasi) | Only "Aries sun sign" |
| Kanni / கன்னி | Virgo moon | Spelling Kannai / Kanya mixed randomly |
| Hastham, 2nd Padam | ஹஸ்தம் | Star without pada when sheet has it |
| Poosam / Pushya | பூசம் | Invented English nicknames |
| Thiruvonam / Sravanam | திருவோணம் | Mixing Malayalam star names casually |
Pick one transliteration style and stick to it across biodata, matrimony bio, and the detailed chart filename. If your priest uses Sanskrit forms (Hasta vs Hastham), mirror the priest's sheet so families do not think there are two different charts.

Birth time accuracy (the #1 silent failure)
Lagnam and Nakshatra Padam can flip with a few minutes' error. Families that cast charts from your biodata will notice mismatches against hospital records later. Prefer the birth certificate / maternity discharge note over "amma remembers around 6." If the family only has an approximate window, write the window honestly: Approx 5:30–6:00 AM IST or simply Birth time unknown.
- Always label timezone as IST for India births — NRI PDFs sometimes drop it.
- Do not "optimize" time for a better Lagnam; it collapses when documents appear.
- Place of birth needs city + state (or country) so longitude is clear for casting.
- Hospital clock vs home clock debates: pick the documented time and note uncertainty privately to the priest if needed.
- After correcting time, regenerate the PDF so old WhatsApp forwards do not circulate.

One-page biodata vs attaching a full jathagam
First WhatsApp share should stay one page: photo, personal, jathagam strip, education, family, short About Me. A multi-page scanned chart is hard to open on older phones and feels like oversharing before mutual interest. Once both families want porutham depth, send a clearly named second PDF.
- Page 1: biodata with Rasi / Nakshatram / Chevvai filled
- Later: detailed jathagam PDF on request
- 10 blurry chart photos in the first chat
Community nuance: some Iyer / Iyengar / Chettiar / Kongu families ask for Gothram and maternal details earlier. Put Gothram on page one; keep maternal grandfather notes short unless your community expects a dedicated line. The full lifestyle layout still belongs on the thirumanam biodata hub— this article stays focused on getting the astrology block right.

How to build the Tamil jathagam biodata PDF
- Collect birth certificate / family jathagam sheet — verify time zone (IST).
- Open /create and choose a Tamil-friendly template.
- Fill personal details, then the full jathagam strip (Rasi → Chevvai).
- Add education, family, About Me — keep astrology readable, not tiny.
- Download PDF and preview on WhatsApp before mass forwards.

Pro Tips
- Bilingual labels: Rasi / ராசி, Nakshatram / நட்சத்திரம் — elders scan faster.
- Always include Padam when your family sheet has it; porutham can shift by pada.
- Place jathagam above the fold on mobile — under photo / personal, before long About Me.
- If sending a detailed chart later, name the file clearly:
Name_Jathagam.pdf. - Free templates → one-page PDF → WhatsApp.
- For Tamil Nadu citizen services and official directories, see tn.gov.in— keep biodata personal facts accurate; do not invent jathagam fields.
- Sample line: "Rasi: Thulam · Star: Swathi 3 · Lagnam: Makaram · Gothram: Srivatsa · Chevvai: Illai".
- Proofread Tamil spelling against the priest's chart — WhatsApp autocorrect breaks names.
Common mistakes
| Better | Avoid |
|---|---|
| Exact birth time or "Unknown" | Guessed "around sunrise" |
| Chevvai Undu / Illai explicit | Blank Chevvai field |
| Rasi + Nakshatram + Padam | Only "zodiac: Virgo" (Western) |
| One-page PDF first | 10-page chart on first forward |
Checklist
- DOB + time + place confirmed from records
- Rasi written (Tamil + English if possible)
- Nakshatram with Padam when known
- Lagnam included for priest speed
- Gothram present (no sagotra risk)
- Chevvai Dosham: Undu / Illai / Partial
- One-page biodata — full chart PDF optional later
- No invented birth time
- Template → PDF → WhatsApp share
- Cross-check spelling against family jathagam sheet
Field-by-field: Rasi, Nakshatram, Lagnam, Gotram, Chevvai
The jathagam strip is five fields most Tamil families treat as a mini checklist. Write each one the way a priest expects to hear it on a phone call — not the way a Western zodiac app labels a sun sign. Below is how to fill each line with bilingual Tamil cues, plus a worked example you can mirror on your PDF biodata.
Rasi (ராசி) — moon sign, not sun sign
Rasi on a Tamil thirumanam biodata means the moon sign at birth. Families match Dina / Rasi porutham from this field. Prefer Vedic Tamil names: Mesham (மேஷம்), Rishabam (ரிஷபம்), Mithunam (மிதுனம்), Katakam (கடகம்), Simham (சிம்மம்), Kanni (கன்னி), Thulam (துலாம்), Viruchikam (விருச்சிகம்), Dhanusu (தனுசு), Makaram (மகரம்), Kumbam (கும்பம்), Meenam (மீனம்). Example line: Rasi: Kanni / கன்னி. Do not write only "Virgo" — elders may assume you meant a Western sun sign and ask again. If your family sheet uses Sanskrit (Kanya) and Tamil (Kanni), pick one pair and keep it consistent with the detailed chart you may send later via kundali details guidance.
Nakshatram + Padam (நட்சத்திரம்)
Nakshatram is the birth star; Padam (1st–4th) is the quarter inside that star. Many porutham engines care about pada for Rajju and Gana nuance. Write: Nakshatram: Hastham / ஹஸ்தம், 2nd Padam. Common Tamil forms: Ashwini, Bharani, Karthikai, Rohini, Mrigasheersham, Thiruvathirai, Punarpoosam, Poosam, Ayilyam, Magam, Pooram, Uthiram, Hastham, Chithirai, Swathi, Visakam, Anusham, Kettai, Moolam, Pooradam, Uthiradam, Thiruvonam, Avittam, Sathayam, Poorattathi, Uthirattathi, Revathi. If your sheet only lists the star without pada, write the star and leave pada blank with a note like "Padam not on family sheet" rather than guessing. Cross-check spelling against the priest's handwritten jathagam before the first WhatsApp forward — see also WhatsApp biodata format.
Lagnam (லக்னம்) — ascendant
Lagnam flips with birth time. Priests often glance at Lagnam before they open a full chart software screen. Example: Lagnam: Simham / சிம்மம். If birth time is unknown, omit a fake Lagnam — write Lagnam: Unknown (birth time not recorded). Inventing an ascendant to look "stronger" is the fastest way to lose trust when hospital papers appear. Pair accurate time with city/state so longitude is clear; NRI families should keep IST labelled when the birth was in India, per NRI marriage biodata habits.
Gotram / Gothram (கோத்திரம்)
Gothram prevents sagotra alliances in many Brahmin, Chettiar, and other lineage-conscious Tamil communities. Write the exact family form: Bharadwaj, Kashyapa, Srivatsa, Atreya, Gautama, Vasishta, and so on. Example: Gothram: Kashyapa. Do not invent a "prestigious" gotra. If maternal gotra is requested in your sub-community, add a second short line rather than mixing both into one ambiguous word. Full lineage field help: gotra & caste in biodata · about my family.
Chevvai Dosham (செவ்வாய் தோஷம்)
State status in one breath: Illai / Undu / Partial. Preferred bilingual: Chevvai Dosham: Illai or Chevvai Dosham: Undu (open to Chevvai match). Traditional Tamil advice often pairs Chevvai with Chevvai; modern families may discuss remedies later — honesty still belongs on page one. Never leave the cell blank.

Worked strip (bride or groom)
DOB: 08 Aug 1997 · Time: 06:18 AM IST · Place: Tiruchirappalli, TN
Rasi: Thulam / துலாம் · Nakshatram: Swathi / சுவாதி, 3rd Padam
Lagnam: Makaram / மகரம் · Gothram: Srivatsa · Chevvai: Illai · Gana: Deva
How priests and families actually read a Tamil biodata
Understanding the scan order helps you design the strip. On WhatsApp, an aunt opens the PDF, zooms once, and either forwards it to the family astrologer or asks for a missing field. The priest rarely reads your About Me first. Typical order: photo sanity check → age/height → DOB + time + place → Rasi + Nakshatram (+ Padam) → Gothram → Chevvai → Lagnam → only then education and family. If Rasi is missing, the PDF often stalls in a group chat with "jathagam illaya?" before anyone praises your career line.
What families filter in under ten seconds
- Same Gothram risk — instant soft reject in many lineages.
- Chevvai blank — treated as possible hide, not as "modern."
- Western-only zodiac labels — triggers a follow-up call for Tamil names.
- Birth time inventively precise ("exactly 5:01") when relatives know it was approximate — trust drops.
- Multi-page chart photos before mutual interest — older phones struggle; one-page biodata wins the first pass. Layout discipline: simple one-page biodata.
What priests do after the forward
Once both sides are interested, the priest (or software the family trusts) recomputes porutham from DOB, time, and place — your Rasi/Nakshatram lines are a convenience filter, not a substitute for casting. That is why inventing Padam or Lagnam backfires: the recomputed chart will disagree with your PDF. Your job on the biodata is accurate inputs and readable Tamil/English labels so the priest does not chase parents for basics. Keep the full lifestyle story on the thirumanam biodata hub; keep this strip honest and scannable. Photo quality still matters for the human filter before astrology: photo guidelines · height, weight & age.
Community nuance: Iyer / Iyengar families may ask Gothram and maternal details earlier; Kongu and Chettiar networks often care about native town plus Gothram; diaspora relatives may need bilingual labels more than elders in Madurai. None of that changes the core rule — birth triad + Rasi + Nakshatram + Chevvai on page one.
Common spelling and transliteration mistakes
Autocorrect and mixed Sanskrit–Tamil habits create false "two charts" drama. Families compare your biodata to the priest's sheet; if Hastham becomes Hasta on one PDF and Atham on another, they think data changed. Pick one transliteration style and reuse it on matrimony sites, WhatsApp captions, and the detailed jathagam filename.
| Prefer | Avoid / why |
|---|---|
| Kanni / கன்னி | Kannai, only "Virgo", random Kanya/Kanni flip mid-PDF |
| Hastham, 2nd Padam / ஹஸ்தம் | Hasta without noting Sanskrit form; inventing padam |
| Poosam / பூசம் | Pushya nickname only; Poosham vs Poosam mismatch vs sheet |
| Thiruvonam / திருவோணம் | Casual Malayalam star labels on a Tamil sheet |
| Chevvai Dosham: Illai | "No dosh", blank cell, or English-only Manglik without Tamil cue |
| Gothram: Bharadwaj | Bharadwaja / Bharadwaj / Bharadwai alternating across messages |
| 11:32 AM IST | 11:32 without IST on NRI forwards; "sunrise" as a fake precision |

Copy-ready sample jathagam blocks
Use these as layout anchors — replace names and chart values with your family sheet. Keep the same field order so priests scanning many PDFs find Rasi in a predictable place. Girl and boy strips share astrology; only the surrounding career/family tone changes (see shaadi biodata for girl · marriage biodata for boy).

What is a Tamil jathagam biodata block?
The jathagam block lists birth chart fields used for porutham matching: Date/Time/Place of birth, Rasi (moon sign), Nakshatram (birth star) with Padam, Lagnam (ascendant), Gothram, and Chevvai Dosham status.
How is this different from the Thirumanam biodata hub?
The thirumanam-biodata-format-tamil hub covers the full Tamil marriage biodata. This page goes deeper only on the jathagam / Rasi / Nakshatram section — field-by-field samples, porutham context, and common astrology mistakes.
Which jathagam fields are mandatory on a Tamil biodata?
Mandatory: DOB, birth time, birth place, Rasi, Nakshatram (ideally with Padam), Gothram, and Chevvai Dosham. Lagnam and Gana are strongly recommended for faster priest review.
What is Chevvai Dosham in a Tamil biodata?
Chevvai Dosham is the Tamil term for Mangal Dosha (Mars affliction). State clearly: Chevvai Undu / Illai (or Partial). Never hide it — families check charts anyway.
Should I attach a full jathagam PDF with the biodata?
Optional. Many families first want a one-page biodata with key fields, then a separate detailed jathagam after mutual interest. Keep WhatsApp first share to one clean page.
What if birth time is unknown?
Write 'Birth time unknown' honestly. Do not invent a time — Lagnam and Padam will be wrong and create distrust later.
Do I need Tamil script for Rasi and Nakshatram names?
Bilingual is best: English names with Tamil in brackets (e.g., Kanni / கன்னி; Hastham / ஹஸ்தம்). Elders and NRI relatives both appreciate clarity.
How do I create a Tamil jathagam biodata PDF free?
Open BiodataBuilder.in/create, fill personal + jathagam fields, pick a template, and download a WhatsApp-ready PDF — no signup.
Conclusion
A strong Tamil jathagam biodata format is accurate birth data plus Rasi, Nakshatram, Lagnam, Gothram, and clear Chevvai status — on one scannable page. Use the thirumanam hub for full layout, then fill astrology carefully here. Export a free PDF template and share on WhatsApp.
