Panchang in Sevan, Gegharkunik, Armenia Fri 30 Apr 1971

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 60°–72° is the 6th, Shukla Shashthi. A day takes the tithi in force at its sunrise, 06:01 here. Panchami ended at 21:34 Thu, before it. Shashthi ends at 21:45, when the lead reaches 72°. The lead passed 0° at the new moon of 25 Apr, so the Moon is waxing: Shukla paksha.

The night of Thu 29 Apr ran from sunset 19:52 Thu to sunrise 06:01, 10 h 9 m. Cut into 15 muhurtas of 40 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:01 to 19:53, splits into 8 choghadiyas of 1 h 44 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:53 to 06:00 Sat, splits into 8 choghadiyas of 1 h 15 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′. Ardra spans 66°40′–80°00′; the Moon entered its pada 4 at 76°40′. It leaves at 06:15, for Punarvasu.

Add the Sun's and the Moon's places among the stars: 15.6° + 79.9° = 95.5°. The sum, cut into 27 parts of 13°20′, gives the yoga: 93°20′–106°40′ is the 8th, Dhriti. It ends at 01:29 Sat, then Shula.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Shashthi is Kaulava and the second Taitila. Kaulava runs until 09:33, when the lead reaches 66°; Taitila until 21:45.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:01 to 06:00 Sat, so the hours after midnight still belong to Shukrawara.

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 15 May, inside the month. The next new moon, 24 May, 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 25 Apr, 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: 26 Mar 1971, 23:23 Fri. Since then the Sun has moved 33.6° round the stars. Vikram Samvat numbers that year 2028; Shaka Samvat numbers it 1893.
