Tithi Today — With End Time, Your Janma Tithi and the Month's List

A tithi is a lunar day, and it is defined precisely: the time the Moon takes to gain twelve degrees on the Sun. Thirty of them make a lunar month, fifteen in the waxing half ending at Purnima and fifteen in the waning half ending at Amavasya.

Because the Moon's speed varies through its orbit, a tithi lasts anywhere from about nineteen to twenty-six hours. It therefore almost never lines up with a calendar day, which is why a tithi today calculator has to give both the tithi running at sunrise and the exact minute it ends.

That end time is the part most calendars leave out and the part that actually matters. A vrat kept on Ekadashi must fall while Ekadashi is running; a ceremony fixed for Panchami is not on Panchami if Panchami ended at eleven in the morning.

The fifteen names repeat in both halves - Pratipada, Dwitiya, Tritiya and so on through Chaturdashi - closing with Purnima in the bright half and Amavasya in the dark. That is the 30 tithi list with names, and the full table sits in the result above.

More useful than the names are the five groups, which repeat every five tithis and decide what each day suits.

Knowing the group is often enough for everyday planning. A Purna tithi suits completing things and holding ceremonies; a Rikta tithi is best used for clearing, cancelling and removing rather than starting. Jaya tithis genuinely do favour competitive situations, which is why litigation dates are often chosen on them.

Each tithi also has a presiding deity - Ganesha on Chaturthi, Shiva on Ashtami and Chaturdashi, Durga on Navami, Vishnu on Dwadashi - which is why particular fasts attach to particular tithis across the month.

Enter your date of birth in the form and the result adds your janma tithi - the lunar day you were born on. A janma tithi calculator matters more in Indian practice than many people realise, because the traditional Hindu birthday follows the tithi and not the Gregorian date.

This is why a grandmother's birthday celebration lands on a different date every year while everyone else's stays fixed. The tithi returns roughly every 354 days rather than every 365, so it moves back by ten to eleven days each year, then jumps forward by about twenty when an extra lunar month is inserted.

Finding your tithi by date of birth is useful beyond the birthday itself. Tithi-based observances - a vrat kept on your janma tithi each month, or the tithi used for shradh after a death - all depend on knowing it. The calculator also gives the next date your tithi returns, so you can mark it.

In south India the equivalent custom uses the birth nakshatra rather than the tithi, and both are given by the Vedic age calculator on this site.

Below the daily card sits the full tithi calendar by month for whichever month and year you choose - every date with the tithi at sunrise, its end time, its group and the day of the week.

Reading a month at once makes the rhythm visible. The tithis run in order, so a fast or a ceremony fixed to a particular tithi appears exactly twice a month - once in the bright half and once in the dark. Ekadashi twice, Chaturthi twice, Ashtami twice.

Two patterns are worth watching for in the table. A date that carries the same tithi as the previous day means a vriddhi tithi, stretched across two sunrises. A tithi missing from the list altogether is a kshaya tithi, which began and ended between two sunrises - and in that month, any observance tied to it moves to the adjacent day by rule.

For festivals and fasts specifically, the dedicated calculators on this site - ekadashi, purnima and amavasya, and the festival calendar - apply the full set of rules rather than the tithi alone.

1. The angle. The Moon's and Sun's sidereal longitudes are computed with the Swiss Ephemeris using the Lahiri ayanamsa, and the difference divided by twelve degrees gives the tithi.

2. At your sunrise. The reading is taken at your own city's sunrise, which is what determines the day's tithi in panchang.

3. The end time. The moment the angle crosses into the next tithi is refined to the minute and converted to your local time.

Most regular Hindu fasts are fixed to a tithi rather than a date, which is why knowing the tithi each morning is so useful. The common ones are worth listing.

Chaturthi. Sankashti Chaturthi in the dark half, broken at moonrise, and Vinayaka Chaturthi in the bright half - both for Ganesha.

Ashtami. Kalashtami in the dark half for Bhairava, and Durga Ashtami in the bright half, most prominently during Navratri.

Ekadashi. Twice a month, for Vishnu - the most widely kept of all the tithi fasts.

Trayodashi. Pradosh vrat, kept at dusk for Shiva, twice a month. On a Monday it becomes Som Pradosh and on a Saturday Shani Pradosh.

Chaturdashi. Masik Shivaratri in the dark half each month, with Maha Shivaratri in Phalguna as the great annual form.

Purnima and Amavasya. The full moon for Satyanarayan katha and the monthly purnima vrat; the new moon for ancestor rites.

The tithi calendar above shows where each of these falls in the month you choose, along with the exact minute each tithi ends - which decides whether the fast is kept on one day or the next.

Because a tithi does not match a solar day, two unusual situations arise every month, and they explain most of the disagreements between printed calendars.

A kshaya tithi is one that begins after one sunrise and ends before the next. It never touches a sunrise, so it never names a day, and it disappears from the calendar that month. A fast tied to it has to be moved, and the rule for which way depends on the specific observance.

A vriddhi tithi is the reverse - one long enough to be running at two consecutive sunrises. It names two days in a row. Again, which of the two is used for an observance depends on the rule for that particular fast; for Ekadashi, for instance, Smarta and Vaishnava households may choose differently.

These cases are why two reputable calendars occasionally differ by a day. Neither is wrong - they are applying different rules to the same astronomical fact. Having the exact end time, as this page gives, lets you check any of them yourself.

This Tithi Calculator in kundli answers the six questions people search most — love or arranged marriage prediction, Tithi Calculator by date of birth, 5th and 7th house connection, inter caste marriage yoga — each with the rule behind it. The Tithi Calculator in kundli above computes your own result free; the sections below explain what it means, and a Tithi Calculator in kundli that shows its working is one you can check against any astrologer.

Tithi Calculator in Kundli — What the Calculator Checks

Tithi Calculator in kundli is not one rule but a set of them. This calculator tests ten love-marriage yogas and five arranged-marriage indications against your actual chart and shows each one as a pass or a fail with the planets behind it.

Love or Arranged Marriage Prediction — Both Sides Scored

An honest love or arranged marriage prediction scores both. The result gives a percentage for each, and when both are high it usually means you meet someone yourself and the families agree.

Tithi Calculator by Date of Birth — Birth Time Matters

For Tithi Calculator by date of birth you also need an exact birth time, because the houses depend on the ascendant, which changes every two hours. With date, time and place, the reading is precise.

The 5th and 7th House Connection — the Core Rule

The 5th and 7th house connection is the heart of the matter: romance linked to marriage. The strongest form is a mutual exchange of their lords, then conjunction, then a mutual aspect.

Inter Caste Marriage Yoga — Rahu and Ketu

Inter caste marriage yoga is read from Rahu or Ketu linked to the 5th house, the 7th house, Venus or the 7th lord. The result names each connection found in your chart, and says plainly when none is present.

If you came to this Tithi Calculator in kundli to check a result from another app, compare the degree, not just the sign — two tools using different ayanamsas will disagree by about a sign near boundaries. This Tithi Calculator in kundli prints Lahiri, the value used, and every intermediate step, so the Tithi Calculator in kundli result can be verified line by line.
