Panchang in Sevan, Gegharkunik, Armenia Sat 1 Apr 1989

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, 07:44 here. Navami ended at 02:12, before it. Dashami ends at 00:33 Sun, when the lead reaches 300°. The lead passed 180° at the full moon of 22 Mar, so the Moon is waning: Krishna paksha.

The night of Fri 31 Mar ran from sunset 20:23 Fri to sunrise 07:44, 11 h 21 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:44 to 20:24, splits into 8 choghadiyas of 1 h 35 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:24 to 07:42 Sun, splits into 8 choghadiyas of 1 h 24 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 Ashadha spans 266°40′–280°00′; the Moon entered its pada 4 at 276°40′. It leaves at 10:13, for Shravana.

Add the Sun's and the Moon's places among the stars: 347.6° + 278.6° = 626.2°, one full turn and 266.2°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 253°20′–266°40′ is the 20th, Shiva. It ends at 08:27, then Siddha.

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 runs until 13:28, when the lead reaches 294°; Vishti until 00:33 Sun.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:44 to 07:42 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: Kumbha gives Phalguna. The Sun enters Meena on 14 Mar, inside the month. The next new moon, 6 Apr, finds it in Meena and begins Chaitra.

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 Apr, with the Sun in Meena, begins Chaitra. Until then this Krishna paksha reads Chaitra here, and Phalguna in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 18 Mar 1988, 06:02 Fri. Since then the Sun has moved 373.6° round the stars. Vikram Samvat numbers that year 2045; Shaka Samvat numbers it 1910.
