Panchang in Sevan, Gegharkunik, Armenia Tue 26 Feb 1907

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 144°–156° is the 13th, Shukla Trayodashi. A day takes the tithi in force at its sunrise, 06:40 here. Dwadashi ended at 06:28 Mon, before it. Trayodashi ends at 08:01, when the lead reaches 156°. The lead passed 0° at the new moon of 12 Feb, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Trayodashi began at 06:28 Mon, before sunrise at 06:41 Mon, and ends at 08:01, after the next sunrise at 06:40. Both days read Trayodashi: it is a vriddhi tithi here.

The night of Mon 25 Feb ran from sunset 17:45 Mon to sunrise 06:40, 12 h 55 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:40 to 17:46, splits into 8 choghadiyas of 1 h 23 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:46 to 06:39 Wed, splits into 8 choghadiyas of 1 h 36 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′. Ashlesha spans 106°40′–120°00′; the Moon entered its pada 1 at 106°40′. It leaves at 03:24 Wed, for Magha.

Add the Sun's and the Moon's places among the stars: 313.8° + 109.2° = 423°, one full turn and 63°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 53°20′–66°40′ is the 5th, Shobhana. It ends at 13:08, then Atiganda.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Trayodashi is Kaulava and the second Taitila. Kaulava ended at 19:19 Mon, when the lead reached 150°; Taitila runs until 08:01.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:40 to 06:39 Wed, so the hours after midnight still belong to Mangalawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 12 Feb 20:42 Tue to 14 Mar 09:04 Thu the Sun stayed in Kumbha, entering Meena at 14 Mar 09:59 Thu, after the new moon. A month with no sankranti is Adhika Phalguna, before Phalguna itself.

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 12 Feb, with the Sun in Kumbha, began Phalguna (Adhik). This Shukla paksha reads Phalguna (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 25 Mar 1906, 02:51 Sun. Since then the Sun has moved 332.9° round the stars. Vikram Samvat numbers that year 1963; Shaka Samvat numbers it 1828.
