Panchang in Myshkin, Yaroslavl Oblast, Russia Tue 17 May 2016

Smartas test Ekadashi at sunrise: it holds sunrise on Tue 17 May only, at 03:58: Tue 17 May. Vaishnavas test arunodaya: Dashami ended at 12:20 Mon, before it (02:22–03:58).

Mohini Ekadashi: every date in Myshkin

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 120°–132° is the 11th, Shukla Ekadashi. A day takes the tithi in force at its sunrise, 03:58 here. Dashami ended at 12:20 Mon, before it. Ekadashi ends at 14:47, when the lead reaches 132°. The lead passed 0° at the new moon of 6 May, so the Moon is waxing: Shukla paksha.

The night of Mon 16 May ran from sunset 20:45 Mon to sunrise 03:58, 7 h 13 m. Cut into 15 muhurtas of 28 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 03:58 to 20:47, splits into 8 choghadiyas of 2 h 6 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:47 to 03:56 Wed, splits into 8 choghadiyas of 53 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′. Uttara Phalguni spans 146°40′–160°00′; the Moon entered its pada 4 at 156°40′. It leaves at 04:49, for Hasta.

Add the Sun's and the Moon's places among the stars: 32.5° + 159.6° = 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 18:52, then Siddhi.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Ekadashi is Vanija and the second Vishti. Vanija ended at 01:32, when the lead reached 126°; Vishti runs until 14:47.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 03:58 to 03:56 Wed, so the hours after midnight still belong to Mangalawara.

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: Mesha gives Vaishakha. The Sun enters Vrishabha on 14 May, inside the month. The next new moon, 5 Jun, finds it in Vrishabha and begins Jyeshtha.

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 6 May, with the Sun in Mesha, began Vaishakha. This Shukla paksha reads Vaishakha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 7 Apr 2016, 14:23 Thu. Since then the Sun has moved 38.5° round the stars. Vikram Samvat numbers that year 2073; Shaka Samvat numbers it 1938.
