Panchang in Sevan, Gegharkunik, Armenia Sat 25 Dec 1982

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, 08:21 here. Navami ended at 06:27, before it. Dashami ends at 05:32 Sun, when the lead reaches 120°. The lead passed 0° at the new moon of 15 Dec, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise.

New Delhi · IST

Sunrise here, 07:11, came before Navami ended at 07:57: this day reads Navami. Dashami ends at 07:02 Sun, before the next sunrise, so no day here reads Dashami: it is kshaya.

Sunrise here, 08:21, came after Navami ended at 06:27: this day reads Dashami.

The night of Fri 24 Dec ran from sunset 17:37 Fri to sunrise 08:21, 14 h 44 m. Cut into 15 muhurtas of 58 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 08:21 to 17:38, 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, 17:38 to 08:21 Sun, 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′. Revati spans 346°40′–360°00′; the Moon entered its pada 4 at 356°40′. It leaves at 11:13, for Ashwini.

Add the Sun's and the Moon's places among the stars: 249.4° + 358.4° = 607.8°, one full turn and 247.8°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 240°00′–253°20′ is the 19th, Parigha. It ends at 17:31, 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 runs until 18:06, when the lead reaches 114°; Garaja until 05:32 Sun.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:21 to 08:21 Sun, so the hours after midnight still belong to Shaniwara.

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, 14 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 15 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: 25 Mar 1982, 14:17 Thu. Since then the Sun has moved 268.6° round the stars. Vikram Samvat numbers that year 2039; Shaka Samvat numbers it 1904.
