Panchang in Sevan, Gegharkunik, Armenia Fri 25 Apr 1975

Hanuman Jayanti follows the tithi at sunrise. Purnima runs from 02:42 on Fri 25 Apr to 23:54 on Fri 25 Apr, so it holds sunrise only on Fri 25 Apr, at 06:08. No text giving Hanuman Jayanti’s time was found; sunrise is Tithika’s convention.

Hanuman Jayanti: every date in Sevan

Purnima follows the tithi at sunrise. Purnima runs from 02:42 on Fri 25 Apr to 23:54 on Fri 25 Apr, so it holds sunrise only on Fri 25 Apr, at 06:08. No text giving Purnima’s time was found; sunrise 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, 06:08 here. Chaturdashi ended at 02:42, before it. Purnima ends at 23:54, when the lead reaches 180°. The lead passed 0° at the new moon of 11 Apr, so the Moon is waxing: Shukla paksha.

The night of Thu 24 Apr ran from sunset 19:47 Thu to sunrise 06:08, 10 h 21 m. Cut into 15 muhurtas of 41 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:08 to 19:48, splits into 8 choghadiyas of 1 h 42 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:48 to 06:06 Sat, splits into 8 choghadiyas of 1 h 17 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 3 at 180°. It leaves at 15:57, for Swati.

Add the Sun's and the Moon's places among the stars: 10.7° + 180.7° = 191.4°. The sum, cut into 27 parts of 13°20′, gives the yoga: 186°40′–200°00′ is the 15th, Vajra. It ends at 19:20, then Siddhi.

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 runs until 13:16, when the lead reaches 174°; Bava until 23:54.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:08 to 06:06 Sat, so the hours after midnight still belong to Shukrawara.

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 14 Apr, inside the month. The next new moon, 11 May, 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 11 Apr, 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: 11 Apr 1975, 20:38 Fri. Since then the Sun has moved 13° round the stars. Vikram Samvat numbers that year 2032; Shaka Samvat numbers it 1897.
