पटना (Patna), Bihar
A free kundli for people born in Patna (25.5941°N, 85.1376°E): enter your date and exact time, and we calculate your lagna, rashi, nakshatra and house chart.

IST (UTC+5:30) is anchored at 82.5°E, near Mirzapur. Patna sits at 85.1376°E, so its local solar time runs roughly 11 minutes ahead of clock time, and that offset carries into the lagna and house cusps.
These figures are calculated from Patna's coordinates (25.5941°N, 85.1376°E) with an astronomical ephemeris, not estimated. All clock times are Indian Standard Time (IST).
| Date (2026) | Sunrise | Sunset | Day length |
|---|---|---|---|
| 20 Mar (equinox) | 05:53 | 18:00 | 12h 7m |
| 21 Jun (longest day) | 04:59 | 18:43 | 13h 44m |
| 23 Sep (equinox) | 05:38 | 17:45 | 12h 7m |
| 21 Dec (shortest day) | 06:31 | 17:03 | 10h 33m |
Day length in Patna swings by 3h 11m between the longest and shortest day, the 12th largest of the 30 cities on this site. Its 21 June sunrise at 04:59 IST is the 2nd earliest of the 30. That is 25 minutes before Delhi's 21 June sunrise.
A worked example of the effect on lagna: at 06:00 IST on 21 June 2026 the sidereal ascendant in Patna is Gemini, and it moves into Cancer at 06:54 IST. At the same latitude on the 82.5°E IST meridian that change happens at 07:05 IST, so in Patna it comes 11 minutes earlier than on the meridian.
The same test in winter: at 06:00 IST on 21 December 2026 the ascendant in Patna is Scorpio, moving into Sagittarius at 06:14 IST, against 06:25 IST on the 82.5°E meridian, so 11 minutes earlier than the meridian. That is a different sign from the June example because the Sun has moved on.
The closest other city on this site to Patna is Varanasi, 219 km away. It has solar time 9 minutes behind Patna, a 21 June sunrise 9 minutes later and a day-length swing 2 minutes smaller.
Method: ephemeris sunrise/sunset (sea level, with refraction); ascendant from mean obliquity and Lahiri ayanamsa. Other software may differ by a minute or two.
Ancient Pataliputra, where the astronomer-mathematician Aryabhata is traditionally placed, since his Kusumapura is generally identified with it.

Patna (Bihar) lies at 85.1376°E, so its local time runs about 11 minutes ahead of IST, which is set at 82.5°E. Lagna and house boundaries depend on that, so the right city matters even though India uses one clock.
Near a sign boundary, yes. By our calculation, on 21 June 2026 the Gemini ascendant in Patna moves into Cancer at 06:54 IST, while at the same latitude on 82.5°E it does so at 07:05 IST. A birth between those two times gets a different lagna depending on the place used.
By our calculation, on 21 June 2026 the Sun rises in Patna at 04:59 IST and sets at 18:43 IST, while on 21 December it rises at 06:31 IST. Vara (weekday) and many panchang calculations start from local sunrise, so for a birth near dawn both the place and the date change the answer.
