Panchang in Sevan, Gegharkunik, Armenia Fri 28 May 1999

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, 06:34 here. Dwadashi ended at 04:37 Thu, before it. Trayodashi ends at 06:54, when the lead reaches 156°. The lead passed 0° at the new moon of 15 May, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Trayodashi began at 04:37 Thu, before sunrise at 06:34 Thu, and ends at 06:54, after the next sunrise at 06:34. Both days read Trayodashi: it is a vriddhi tithi here.

The night of Thu 27 May ran from sunset 21:19 Thu to sunrise 06:34, 9 h 15 m. Cut into 15 muhurtas of 37 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:34 to 21:20, 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 night here, 21:20 to 06:33 Sat, splits into 8 choghadiyas of 1 h 9 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′. Swati spans 186°40′–200°00′; the Moon entered its pada 4 at 196°40′. It leaves at 09:58, for Vishakha.

Add the Sun's and the Moon's places among the stars: 42.5° + 198.3° = 240.8°. The sum, cut into 27 parts of 13°20′, gives the yoga: 240°00′–253°20′ is the 19th, Parigha. It ends at 06:01 Sat, then Shiva.

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 17:45 Thu, when the lead reached 150°; Taitila runs until 06:54.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:34 to 06:33 Sat, so the hours after midnight still belong to Shukrawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 15 May 17:05 Sat to 14 Jun 00:02 Mon the Sun stayed in Vrishabha, entering Mithuna at 15 Jun 14:08 Tue, after the new moon. A month with no sankranti is Adhika Jyeshtha, before Jyeshtha 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 15 May, with the Sun in Vrishabha, began Jyeshtha (Adhik). This Shukla paksha reads Jyeshtha (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 17 Mar 1999, 22:47 Wed. Since then the Sun has moved 69.6° round the stars. Vikram Samvat numbers that year 2056; Shaka Samvat numbers it 1921.
