Panchang in Sevan, Gegharkunik, Armenia Tue 19 Dec 2045

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 108°–120° is the 10th, Shukla Dashami. A day takes the tithi in force at its sunrise, 08:18 here. Navami ended at 08:14 Mon, before it. Dashami ends at 09:30, when the lead reaches 120°. The lead passed 0° at the new moon of 8 Dec, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Dashami began at 08:14 Mon, before sunrise at 08:18 Mon, and ends at 09:30, after the next sunrise at 08:18. Both days read Dashami: it is a vriddhi tithi here.

The night of Mon 18 Dec ran from sunset 17:35 Mon to sunrise 08:18, 14 h 43 m. Cut into 15 muhurtas of 58 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 08:18 to 17:35, splits into 8 choghadiyas of 1 h 9 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:35 to 08:19 Wed, splits into 8 choghadiyas of 1 h 50 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′. Ashwini spans 0°00′–13°20′; the Moon entered its pada 1 at 0°. It leaves at 04:35 Wed, for Bharani.

Add the Sun's and the Moon's places among the stars: 243.2° + 2.6° = 245.8°. The sum, cut into 27 parts of 13°20′, gives the yoga: 240°00′–253°20′ is the 19th, Parigha. It ends at 21:38, then Shiva.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dashami is Taitila and the second Garaja. Taitila ended at 20:58 Mon, when the lead reached 114°; Garaja runs until 09:30.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:18 to 08:19 Wed, so the hours after midnight still belong to Mangalawara.

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: Vrishchika gives Margashirsha. The Sun enters Dhanu on 16 Dec, inside the month. The next new moon, 7 Jan, finds it in Dhanu and begins Pausha.

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 8 Dec, with the Sun in Vrishchika, began Margashirsha. This Shukla paksha reads Margashirsha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 18 Mar 2045, 21:14 Sat. Since then the Sun has moved 269.2° round the stars. Vikram Samvat numbers that year 2102; Shaka Samvat numbers it 1967.
