Panchang in Sevan, Gegharkunik, Armenia Sun 14 May 1978

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, 05:45 here. Shashthi ended at 20:27 Sat, before it. Saptami ends at 22:41, when the lead reaches 84°. The lead passed 0° at the new moon of 7 May, so the Moon is waxing: Shukla paksha.

The night of Sat 13 May ran from sunset 20:07 Sat to sunrise 05:45, 9 h 38 m. Cut into 15 muhurtas of 38 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:45 to 20:08, splits into 8 choghadiyas of 1 h 47 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:08 to 05:44 Mon, splits into 8 choghadiyas of 1 h 12 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′. Pushya spans 93°20′–106°40′; the Moon entered its pada 4 at 103°20′. It leaves at 07:53, for Ashlesha.

Add the Sun's and the Moon's places among the stars: 29.4° + 105.6° = 135°. The sum, cut into 27 parts of 13°20′, gives the yoga: 133°20′–146°40′ is the 11th, Vriddhi. It ends at 03:26 Mon, then Dhruva.

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 runs until 09:36, when the lead reaches 78°; Vanija until 22:41.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:45 to 05:44 Mon, so the hours after midnight still belong to Raviwara.

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, 5 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: 7 Apr 1978, 19:15 Fri. Since then the Sun has moved 35.5° round the stars. Vikram Samvat numbers that year 2035; Shaka Samvat numbers it 1900.
