Panchang in Sevan, Gegharkunik, Armenia Fri 27 May 2011

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 288°–300° is the 25th, Krishna Dashami. A day takes the tithi in force at its sunrise, 06:34 here. Navami ended at 15:07 Thu, before it. Dashami ends at 17:31, when the lead reaches 300°. The lead passed 180° at the full moon of 17 May, so the Moon is waning: Krishna paksha.

The night of Thu 26 May ran from sunset 21:19 Thu to sunrise 06:34, 9 h 15 m. Cut into 15 muhurtas of 37 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:34 to 21:20, splits into 8 choghadiyas of 1 h 50 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 21:20 to 06:34 Sat, splits into 8 choghadiyas of 1 h 9 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 Bhadrapada spans 333°20′–346°40′; the Moon entered its pada 1 at 333°20′. It leaves at 03:13 Sat, for Revati.

Add the Sun's and the Moon's places among the stars: 41.4° + 336.5° = 377.9°, one full turn and 17.9°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 13°20′–26°40′ is the 2nd, Priti. It ends at 22:59, then Ayushmana.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dashami is Vanija and the second Vishti. Vanija ended at 04:19, when the lead reached 294°; Vishti runs until 17:31.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:34 to 06:34 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: Mesha gives Vaishakha. The Sun enters Vrishabha on 15 May, inside the month. The next new moon, 2 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 2 Jun, with the Sun in Vrishabha, begins Jyeshtha. Until then this Krishna paksha reads Jyeshtha here, and Vaishakha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 3 Apr 2011, 19:32 Sun. Since then the Sun has moved 51.9° round the stars. Vikram Samvat numbers that year 2068; Shaka Samvat numbers it 1933.
