Panchang in Sevan, Gegharkunik, Armenia Sun 15 Apr 1990

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 228°–240° is the 20th, Krishna Panchami. A day takes the tithi in force at its sunrise, 07:22 here. Chaturthi ended at 17:40 Sat, before it. Panchami ends at 19:59, when the lead reaches 240°. The lead passed 180° at the full moon of 10 Apr, so the Moon is waning: Krishna paksha.

The night of Sat 14 Apr ran from sunset 20:37 Sat to sunrise 07:22, 10 h 45 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:22 to 20:38, splits into 8 choghadiyas of 1 h 39 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:38 to 07:20 Mon, splits into 8 choghadiyas of 1 h 20 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′. Jyeshtha spans 226°40′–240°00′; the Moon entered its pada 3 at 233°20′. It leaves at 16:40, for Mula.

Add the Sun's and the Moon's places among the stars: 1.1° + 235.4° = 236.5°. The sum, cut into 27 parts of 13°20′, gives the yoga: 226°40′–240°00′ is the 18th, Variyana. It ends at 13:51, then Parigha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Panchami is Kaulava and the second Taitila. Kaulava ended at 06:52, when the lead reached 234°; Taitila runs until 19:59.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:22 to 07:20 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: Meena gives Chaitra. The Sun enters Mesha on 14 Apr, inside the month. The next new moon, 25 Apr, finds it in Mesha and begins Vaishakha.

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, begins Vaishakha. Until then this Krishna paksha reads Vaishakha here, and Chaitra in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 27 Mar 1990, 00:48 Tue. Since then the Sun has moved 18.9° round the stars. Vikram Samvat numbers that year 2047; Shaka Samvat numbers it 1912.
