Panchang in Polatlı, Ankara, Turkey Mon 5 Oct 2020

The Sankashti fast is broken at moonrise. Chaturthi runs from 07:32 on Mon 5 Oct to 10:02 on Tue 6 Oct, so it holds moonrise only on Mon 5 Oct, at 20:27. No text giving Sankashti Chaturthi’s time was found; moonrise is Tithika’s convention.

Sankashti Chaturthi: every date in Polatlı

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, 06:51 here. Dwitiya ended at 04:58 Sun, before it. Tritiya ends at 07:32, when the lead reaches 216°. The lead passed 180° at the full moon of 2 Oct, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Tritiya began at 04:58 Sun, before sunrise at 06:50 Sun, and ends at 07:32, after the next sunrise at 06:51. Both days read Tritiya: it is a vriddhi tithi here.

The night of Sun 4 Oct ran from sunset 18:28 Sun to sunrise 06:51, 12 h 23 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:51 to 18:27, splits into 8 choghadiyas of 1 h 27 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:27 to 06:52 Tue, splits into 8 choghadiyas of 1 h 33 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′. Bharani spans 13°20′–26°40′; the Moon entered its pada 4 at 23°20′. It leaves at 12:26, for Krittika.

Add the Sun's and the Moon's places among the stars: 168.2° + 23.9° = 192.1°. The sum, cut into 27 parts of 13°20′, gives the yoga: 186°40′–200°00′ is the 15th, Vajra. It ends at 21:33, then Siddhi.

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 18:15 Sun, when the lead reached 210°; Vishti runs until 07:32.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:51 to 06:52 Tue, so the hours after midnight still belong to Somawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 17 Sep 14:00 Thu to 16 Oct 22:31 Fri the Sun stayed in Kanya, entering Tula at 17 Oct 04:35 Sat, after the new moon. A month with no sankranti is Adhika Ashwina, before Ashwina itself.

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 16 Oct, with the Sun in Kanya, begins Ashwina (Adhik). Until then this Krishna paksha reads Ashwina (Adhik) here, and Ashwina (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 24 Mar 2020, 12:28 Tue. Since then the Sun has moved 188.1° round the stars. Vikram Samvat numbers that year 2077; Shaka Samvat numbers it 1942.
