Panchang in Sevan, Gegharkunik, Armenia Sat 28 Mar 2048

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, 06:49 here. Dwadashi ended at 11:51 Fri, before it. Trayodashi ends at 10:32, when the lead reaches 156°. The lead passed 0° at the new moon of 14 Mar, so the Moon is waxing: Shukla paksha.

The night of Fri 27 Mar ran from sunset 19:19 Fri to sunrise 06:49, 11 h 30 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:49 to 19:20, splits into 8 choghadiyas of 1 h 33 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:20 to 06:47 Sun, splits into 8 choghadiyas of 1 h 25 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 Phalguni spans 133°20′–146°40′; the Moon entered its pada 2 at 136°40′. It leaves at 22:27, for Uttara Phalguni.

Add the Sun's and the Moon's places among the stars: 343.6° + 137.6° = 481.2°, one full turn and 121.2°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 120°00′–133°20′ is the 10th, Ganda. It ends at 02:21 Sun, then Vriddhi.

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 23:17 Fri, when the lead reached 150°; Taitila runs until 10:32.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:49 to 06:47 Sun, so the hours after midnight still belong to Shaniwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 14 Mar 18:27 Sat to 13 Apr 09:19 Mon the Sun stayed in Meena, entering Mesha at 13 Apr 23:17 Mon, after the new moon. A month with no sankranti is Adhika Chaitra, before Chaitra 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 14 Mar, with the Sun in Meena, began Chaitra (Adhik). This Shukla paksha reads Chaitra (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 14 Mar 2048, 18:27 Sat. Since then the Sun has moved 13.4° round the stars. Vikram Samvat numbers that year 2105; Shaka Samvat numbers it 1970.
