Panchang in Sevan, Gegharkunik, Armenia Thu 22 Apr 1915

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 72°–84° is the 7th, Shukla Saptami. A day takes the tithi in force at its sunrise, 05:13 here. Shashthi ended at 04:20 Wed, before it. Saptami ends at 06:01, when the lead reaches 84°. The lead passed 0° at the new moon of 14 Apr, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Saptami began at 04:20 Wed, before sunrise at 05:14 Wed, and ends at 06:01, after the next sunrise at 05:13. Both days read Saptami: it is a vriddhi tithi here.

The night of Wed 21 Apr ran from sunset 18:43 Wed to sunrise 05:13, 10 h 30 m. Cut into 15 muhurtas of 42 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:13 to 18:44, splits into 8 choghadiyas of 1 h 41 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:44 to 05:11 Fri, splits into 8 choghadiyas of 1 h 18 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′. Punarvasu spans 80°00′–93°20′; the Moon entered its pada 4 at 90°. It leaves at 08:09, for Pushya.

Add the Sun's and the Moon's places among the stars: 8.2° + 91.8° = 100°. The sum, cut into 27 parts of 13°20′, gives the yoga: 93°20′–106°40′ is the 8th, Dhriti. It ends at 17:08, then Shula.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Saptami is Garaja and the second Vanija. Garaja ended at 17:15 Wed, when the lead reached 78°; Vanija runs until 06:01.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:13 to 05:11 Fri, so the hours after midnight still belong to Guruwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 14 Apr 14:35 Wed to 14 May 06:30 Fri the Sun stayed in Mesha, entering Vrishabha at 14 May 16:42 Fri, after the new moon. A month with no sankranti is Adhika Vaishakha, before Vaishakha 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 Apr, with the Sun in Mesha, began Vaishakha (Adhik). This Shukla paksha reads Vaishakha (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 15 Mar 1915, 22:41 Mon. Since then the Sun has moved 36.7° round the stars. Vikram Samvat numbers that year 1972; Shaka Samvat numbers it 1837.
