Panchang in Sevan, Gegharkunik, Armenia Mon 23 May 1910

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 156°–168° is the 14th, Shukla Chaturdashi. A day takes the tithi in force at its sunrise, 04:37 here. Trayodashi ended at 03:45 Sun, before it. Chaturdashi ends at 06:17, when the lead reaches 168°. The lead passed 0° at the new moon of 9 May, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Chaturdashi began at 03:45 Sun, before sunrise at 04:38 Sun, and ends at 06:17, after the next sunrise at 04:37. Both days read Chaturdashi: it is a vriddhi tithi here.

The night of Sun 22 May ran from sunset 19:15 Sun to sunrise 04:37, 9 h 22 m. Cut into 15 muhurtas of 37 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 04:37 to 19:15, splits into 8 choghadiyas of 1 h 49 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:15 to 04:36 Tue, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Vishakha spans 200°00′–213°20′; the Moon entered its pada 2 at 203°20′. It leaves at 20:05, for Anuradha.

Add the Sun's and the Moon's places among the stars: 38.4° + 205.7° = 244.1°. The sum, cut into 27 parts of 13°20′, gives the yoga: 240°00′–253°20′ is the 19th, Parigha. It ends at 21:50, then Shiva.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Garaja and the second Vanija. Garaja ended at 17:02 Sun, when the lead reached 162°; Vanija runs until 06:17.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 04:37 to 04:36 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: Mesha gives Vaishakha. The Sun enters Vrishabha on 14 May, inside the month. The next new moon, 7 Jun, finds it in Vrishabha and begins Jyeshtha.

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 May, with the Sun in Mesha, began Vaishakha. This Shukla paksha reads Vaishakha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 10 Apr 1910, 00:24 Sun. Since then the Sun has moved 41.9° round the stars. Vikram Samvat numbers that year 1967; Shaka Samvat numbers it 1832.
