Panchang in Sevan, Gegharkunik, Armenia Thu 17 Oct 2013

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, 07:13 here. Trayodashi ended at 04:58, before it. Chaturdashi ends at 04:04 Fri, when the lead reaches 168°. The lead passed 0° at the new moon of 5 Oct, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise.

Sunrise here, 06:23, came before Trayodashi ended at 06:28: this day reads Trayodashi. Chaturdashi ends at 05:34 Fri, before the next sunrise, so no day here reads Chaturdashi: it is kshaya.

Sunrise here, 07:13, came after Trayodashi ended at 04:58: this day reads Chaturdashi.

The night of Wed 16 Oct ran from sunset 18:18 Wed to sunrise 07:13, 12 h 55 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:13 to 18:17, splits into 8 choghadiyas of 1 h 23 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:17 to 07:14 Fri, splits into 8 choghadiyas of 1 h 37 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 Bhadrapada spans 333°20′–346°40′; the Moon entered its pada 2 at 336°40′. It leaves at 00:22 Fri, for Revati.

Add the Sun's and the Moon's places among the stars: 179.9° + 337° = 516.9°, one full turn and 156.9°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 146°40′–160°00′ is the 12th, Dhruva. It ends at 12:20, then Vyaghata.

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 16:28, when the lead reaches 162°; Vanija until 04:04 Fri.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:13 to 07:14 Fri, so the hours after midnight still belong to Guruwara.

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: Kanya gives Ashwina. The Sun enters Tula on 17 Oct, inside the month. The next new moon, 3 Nov, finds it in Tula and begins Kartika.

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 5 Oct, with the Sun in Kanya, began Ashwina. This Shukla paksha reads Ashwina in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 10 Apr 2013, 13:35 Wed. Since then the Sun has moved 183.3° round the stars. Vikram Samvat numbers that year 2070; Shaka Samvat numbers it 1935.
