Panchang in Myshkin, Yaroslavl Oblast, Russia Fri 14 Apr 2017

The Sun enters Mesha at 23:34 Thu, after sunset (19:33 Thu), so the next day keeps it: Fri 14 Apr. No text giving Mesha Sankranti’s time was found; sankranti is Tithika’s convention.

The Sankashti fast is broken at moonrise. Chaturthi runs from 14:53 on Fri 14 Apr to 17:18 on Sat 15 Apr, so it holds moonrise only on Fri 14 Apr, at 22:57. No text giving Sankashti Chaturthi’s time was found; moonrise is Tithika’s convention.

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 204°–216° is the 18th, Krishna Tritiya. A day takes the tithi in force at its sunrise, 05:18 here. Dwitiya ended at 12:40 Thu, before it. Tritiya ends at 14:53, when the lead reaches 216°. The lead passed 180° at the full moon of 11 Apr, so the Moon is waning: Krishna paksha.

The night of Thu 13 Apr ran from sunset 19:33 Thu to sunrise 05:18, 9 h 45 m. Cut into 15 muhurtas of 39 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:18 to 19:35, splits into 8 choghadiyas of 1 h 47 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:35 to 05:15 Sat, splits into 8 choghadiyas of 1 h 12 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′. Vishakha spans 200°00′–213°20′; the Moon entered its pada 4 at 210°. It leaves at 08:16, for Anuradha.

Add the Sun's and the Moon's places among the stars: 0.2° + 211.9° = 212.1°. The sum, cut into 27 parts of 13°20′, gives the yoga: 200°00′–213°20′ is the 16th, Siddhi. It ends at 07:36, then Vyatipata.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Tritiya is Vanija and the second Vishti. Vanija ended at 01:45, when the lead reached 210°; Vishti runs until 14:53.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:18 to 05:15 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 13 Apr, inside the month. The next new moon, 26 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 26 Apr, with the Sun in Mesha, begins Vaishakha. Until then this Krishna paksha reads Vaishakha here, and Chaitra in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 28 Mar 2017, 05:57 Tue. Since then the Sun has moved 16.7° round the stars. Vikram Samvat numbers that year 2074; Shaka Samvat numbers it 1939.
