Panchang in Sevan, Gegharkunik, Armenia Mon 16 May 2016

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 108°–120° is the 10th, Shukla Dashami. A day takes the tithi in force at its sunrise, 05:42 here. Navami ended at 11:11 Sun, before it. Dashami ends at 13:20, when the lead reaches 120°. The lead passed 0° at the new moon of 6 May, so the Moon is waxing: Shukla paksha.

The night of Sun 15 May ran from sunset 20:09 Sun to sunrise 05:42, 9 h 33 m. Cut into 15 muhurtas of 38 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:42 to 20:10, splits into 8 choghadiyas of 1 h 48 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:10 to 05:41 Tue, splits into 8 choghadiyas of 1 h 11 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 1 at 146°40′. It leaves at 05:49 Tue, for Hasta.

Add the Sun's and the Moon's places among the stars: 31.5° + 148.1° = 179.6°. The sum, cut into 27 parts of 13°20′, gives the yoga: 173°20′–186°40′ is the 14th, Harshana. It ends at 18:51, then Vajra.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dashami is Taitila and the second Garaja. Taitila ended at 00:12, when the lead reached 114°; Garaja runs until 13:20.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:42 to 05:41 Tue, so the hours after midnight still belong to Somawara.

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, 15:23 Thu. Since then the Sun has moved 37.5° round the stars. Vikram Samvat numbers that year 2073; Shaka Samvat numbers it 1938.
