Panchang in Sevan, Gegharkunik, Armenia Mon 16 May 1921

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 108°–120° is the 10th, Shukla Dashami. A day takes the tithi in force at its sunrise, 04:43 here. Navami ended at 03:27, before it. Dashami ends at 01:52 Tue, when the lead reaches 120°. The lead passed 0° at the new moon of 7 May, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise.

Sunrise here, 05:30, came before Navami ended at 05:57: this day reads Navami. Dashami ends at 04:22 Tue, before the next sunrise, so no day here reads Dashami: it is kshaya.

Sunrise here, 04:43, came after Navami ended at 03:27: this day reads Dashami.

The night of Sun 15 May ran from sunset 19:08 Sun to sunrise 04:43, 9 h 35 m. Cut into 15 muhurtas of 38 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 04:43 to 19:09, splits into 8 choghadiyas of 1 h 48 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:09 to 04:42 Tue, splits into 8 choghadiyas of 1 h 11 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 3 at 140°. It leaves at 15:17, for Uttara Phalguni.

Add the Sun's and the Moon's places among the stars: 31.9° + 140.6° = 172.5°. The sum, cut into 27 parts of 13°20′, gives the yoga: 160°00′–173°20′ is the 13th, Vyaghata. It ends at 06:09, then Harshana.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dashami is Taitila and the second Garaja. Taitila runs until 14:37, when the lead reaches 114°; Garaja until 01:52 Tue.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 04:43 to 04:42 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, 6 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 7 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: 8 Apr 1921, 12:04 Fri. Since then the Sun has moved 36.7° round the stars. Vikram Samvat numbers that year 1978; Shaka Samvat numbers it 1843.
