Panchang in Chahārbāgh, Alborz Province, Iran Sun 6 Apr 2031

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 156°–168° is the 14th, Shukla Chaturdashi. A day takes the tithi in force at its sunrise, 05:46 here. Trayodashi ended at 22:57 Sat, before it. Chaturdashi ends at 22:10, when the lead reaches 168°. The lead passed 0° at the new moon of 23 Mar, so the Moon is waxing: Shukla paksha.

The night of Sat 5 Apr ran from sunset 18:31 Sat to sunrise 05:46, 11 h 15 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:46 to 18:32, splits into 8 choghadiyas of 1 h 35 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:32 to 05:45 Mon, splits into 8 choghadiyas of 1 h 24 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′. Uttara Phalguni spans 146°40′–160°00′; the Moon entered its pada 2 at 150°. It leaves at 21:19, for Hasta.

Add the Sun's and the Moon's places among the stars: 351.8° + 151.3° = 503.1°, one full turn and 143.1°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 133°20′–146°40′ is the 11th, Vriddhi. It ends at 11:44, then Dhruva.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Garaja and the second Vanija. Garaja runs until 10:38, when the lead reaches 162°; Vanija until 22:10.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:46 to 05:45 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, 21 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 23 Mar, with the Sun in Meena, began Chaitra. This Shukla paksha reads Chaitra in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 23 Mar 2031, 07:19 Sun. Since then the Sun has moved 13.8° round the stars. Vikram Samvat numbers that year 2088; Shaka Samvat numbers it 1953.
