Panchang in Sevan, Gegharkunik, Armenia Sun 23 Aug 2009

Ganesha’s puja is done at madhyahna, the middle fifth of the day. Chaturthi runs from 06:27 on Sun 23 Aug to 04:41 on Mon 24 Aug, so only Sunday’s madhyahna (12:41–15:23) falls within it.

Ganesh Chaturthi: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 36°–48° is the 4th, Shukla Chaturthi. A day takes the tithi in force at its sunrise, 07:18 here. Tritiya ended at 06:27, before it. Chaturthi ends at 04:41 Mon, when the lead reaches 48°. The lead passed 0° at the new moon of 20 Aug, so the Moon is waxing: Shukla paksha.

Sunrise here, 05:54, came before Tritiya ended at 06:57: this day reads Tritiya. Chaturthi ends at 05:11 Mon, before the next sunrise, so no day here reads Chaturthi: it is kshaya.

Sunrise here, 07:18, came after Tritiya ended at 06:27: this day reads Chaturthi.

The night of Sat 22 Aug ran from sunset 20:47 Sat to sunrise 07:18, 10 h 31 m. Cut into 15 muhurtas of 42 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:18 to 20:46, splits into 8 choghadiyas of 1 h 41 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:46 to 07:19 Mon, splits into 8 choghadiyas of 1 h 19 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′. Hasta spans 160°00′–173°20′; the Moon entered its pada 1 at 160°. It leaves at 01:49 Mon, for Chitra.

Add the Sun's and the Moon's places among the stars: 126.1° + 162.6° = 288.7°. The sum, cut into 27 parts of 13°20′, gives the yoga: 280°00′–293°20′ is the 22nd, Sadhya. It ends at 14:44, then Shubha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturthi is Vanija and the second Vishti. Vanija runs until 17:29, when the lead reaches 42°; Vishti until 04:41 Mon.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:18 to 07:19 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: Simha gives Bhadrapada. The Sun enters Kanya on 16 Sep, inside the month. The next new moon, 18 Sep, finds it in Kanya and begins Ashwina.

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 20 Aug, with the Sun in Simha, began Bhadrapada. This Shukla paksha reads Bhadrapada in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 26 Mar 2009, 20:05 Thu. Since then the Sun has moved 144° round the stars. Vikram Samvat numbers that year 2066; Shaka Samvat numbers it 1931.
