Panchang in Sevan, Gegharkunik, Armenia Mon 2 Feb 1959

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, 08:09 here. Navami ended at 08:08, before it. Dashami ends at 06:12 Tue, when the lead reaches 300°. The lead passed 180° at the full moon of 24 Jan, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise.

The night of Sun 1 Feb ran from sunset 18:17 Sun to sunrise 08:09, 13 h 52 m. Cut into 15 muhurtas of 55 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 08:09 to 18:18, splits into 8 choghadiyas of 1 h 16 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:18 to 08:08 Tue, splits into 8 choghadiyas of 1 h 43 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′. Anuradha spans 213°20′–226°40′; the Moon entered its pada 2 at 216°40′. It leaves at 00:09 Tue, for Jyeshtha.

Add the Sun's and the Moon's places among the stars: 289.3° + 217.3° = 506.6°, one full turn and 146.6°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 133°20′–146°40′ is the 11th, Vriddhi. It ends at 08:18, then Dhruva.

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 19:09, when the lead reaches 294°; Vishti until 06:12 Tue.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:09 to 08:08 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: Dhanu gives Pausha. The Sun enters Makara on 14 Jan, inside the month. The next new moon, 7 Feb, finds it in Makara and begins Magha.

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 7 Feb, with the Sun in Makara, begins Magha. Until then this Krishna paksha reads Magha here, and Pausha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 20 Mar 1958, 13:49 Thu. Since then the Sun has moved 313.3° round the stars. Vikram Samvat numbers that year 2015; Shaka Samvat numbers it 1880.
