Panchang in Sevan, Gegharkunik, Armenia Sat 21 Nov 1981

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, 07:52 here. Navami ended at 07:11 Fri, before it. Dashami ends at 08:08, when the lead reaches 300°. The lead passed 180° at the full moon of 12 Nov, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Dashami began at 07:11 Fri, before sunrise at 07:51 Fri, and ends at 08:08, after the next sunrise at 07:52. Both days read Dashami: it is a vriddhi tithi here.

The night of Fri 20 Nov ran from sunset 17:39 Fri to sunrise 07:52, 14 h 13 m. Cut into 15 muhurtas of 56 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:52 to 17:38, splits into 8 choghadiyas of 1 h 13 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:38 to 07:54 Sun, 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 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 3 at 153°20′. It leaves at 17:31, for Hasta.

Add the Sun's and the Moon's places among the stars: 215.1° + 155° = 370.1°, one full turn and 10.1°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 0°00′–13°20′ is the 1st, Vishkambha. It ends at 13:32, then Priti.

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 19:35 Fri, when the lead reached 294°; Vishti runs until 08:08.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:52 to 07:54 Sun, so the hours after midnight still belong to Shaniwara.

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: Tula gives Kartika. The Sun enters Vrishchika on 16 Nov, inside the month. The next new moon, 26 Nov, finds it in Vrishchika and begins Margashirsha.

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 Nov, with the Sun in Vrishchika, begins Margashirsha. Until then this Krishna paksha reads Margashirsha here, and Kartika in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 5 Apr 1981, 01:19 Sun. Since then the Sun has moved 223.7° round the stars. Vikram Samvat numbers that year 2038; Shaka Samvat numbers it 1903.
