Hanuman Jayanti follows the tithi at sunrise. Purnima runs from 12:09 on Fri 12 Apr to 08:51 on Sat 13 Apr, so it holds sunrise only on Sat 13 Apr, at 06:24. No text giving Hanuman Jayanti’s time was found; sunrise is Tithika’s convention.

The Sun enters Mesha at 10:57, between sunrise (06:24) and sunset (19:36): Sat 13 Apr. No text giving Mesha Sankranti’s time was found; sankranti is Tithika’s convention.

Purnima: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 168°–180° is the 15th, Shukla Purnima. A day takes the tithi in force at its sunrise, 06:24 here. Chaturdashi ended at 12:09 Fri, before it. Purnima ends at 08:51, when the lead reaches 180°. The lead passed 0° at the new moon of 29 Mar, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Pratipada began at 08:51 and ended at 05:21 Sun, between the sunrises of 06:24 and 06:23 Sun. Saturday reads Purnima and Sunday reads Dwitiya: Pratipada is a kshaya tithi here.

The night of Fri 12 Apr ran from sunset 19:35 Fri to sunrise 06:24, 10 h 49 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:24 to 19:36, splits into 8 choghadiyas of 1 h 39 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:36 to 06:23 Sun, splits into 8 choghadiyas of 1 h 20 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Chitra spans 173°20′–186°40′; the Moon entered its pada 2 at 176°40′. It leaves at 19:39, for Swati.

Add the Sun's and the Moon's places among the stars: 359.8° + 178.4° = 538.2°, one full turn and 178.2°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 173°20′–186°40′ is the 14th, Harshana. It ends at 19:07, then Vajra.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Purnima is Vishti and the second Bava. Vishti ended at 22:32 Fri, when the lead reached 174°; Bava runs until 08:51.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:24 to 06:23 Sun, so the hours after midnight still belong to Shaniwara.

An amanta month runs from new moon to new moon and takes its name from the rashi the Sun is in at the new moon that begins it: Meena gives Chaitra. The Sun enters Mesha on 13 Apr, inside the month. The next new moon, 27 Apr, finds it in Mesha and begins Vaishakha.

A purnimanta month runs from full moon to full moon, so its waning half comes first. It shares its name with the amanta month that its second half falls in: the new moon of 29 Mar, with the Sun in Meena, began Chaitra. This Shukla paksha reads Chaitra in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 29 Mar 1968, 02:47 Fri. Since then the Sun has moved 14.9° round the stars. Vikram Samvat numbers that year 2025; Shaka Samvat numbers it 1890.
