Panchang in Sevan, Gegharkunik, Armenia Mon 11 Dec 1950

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 24°–36° is the 3rd, Shukla Tritiya. A day takes the tithi in force at its sunrise, 07:12 here. Dwitiya ended at 05:02, before it. Tritiya ends at 01:53 Tue, when the lead reaches 36°. The lead passed 0° at the new moon of 9 Dec, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise.

Sunrise here, 07:03, came before Dwitiya ended at 07:32: this day reads Dwitiya. Tritiya ends at 04:23 Tue, before the next sunrise, so no day here reads Tritiya: it is kshaya.

Sunrise here, 07:12, came after Dwitiya ended at 05:02: this day reads Tritiya.

The night of Sun 10 Dec ran from sunset 16:33 Sun to sunrise 07:12, 14 h 39 m. Cut into 15 muhurtas of 58 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:12 to 16:33, splits into 8 choghadiyas of 1 h 10 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 16:33 to 07:13 Tue, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Purva Ashadha spans 253°20′–266°40′; the Moon entered its pada 3 at 260°. It leaves at 16:55, for Uttara Ashadha.

Add the Sun's and the Moon's places among the stars: 235.4° + 260.6° = 496°, one full turn and 136°. 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 23:19, then Dhruva.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Tritiya is Taitila and the second Garaja. Taitila runs until 15:23, when the lead reaches 30°; Garaja until 01:53 Tue.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:12 to 07:13 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: Vrishchika gives Margashirsha. The Sun enters Dhanu on 15 Dec, inside the month. The next new moon, 7 Jan, finds it in Dhanu and begins Pausha.

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 9 Dec, with the Sun in Vrishchika, began Margashirsha. This Shukla paksha reads Margashirsha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 18 Mar 1950, 18:20 Sat. Since then the Sun has moved 261.1° round the stars. Vikram Samvat numbers that year 2007; Shaka Samvat numbers it 1872.
