Panchang in Sevan, Gegharkunik, Armenia Thu 16 May 2013

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 60°–72° is the 6th, Shukla Shashthi. A day takes the tithi in force at its sunrise, 05:42 here. Panchami ended at 16:13 Wed, before it. Shashthi ends at 18:20, when the lead reaches 72°. The lead passed 0° at the new moon of 10 May, so the Moon is waxing: Shukla paksha.

The night of Wed 15 May ran from sunset 20:09 Wed to sunrise 05:42, 9 h 33 m. Cut into 15 muhurtas of 38 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:42 to 20:10, splits into 8 choghadiyas of 1 h 48 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:10 to 05:41 Fri, splits into 8 choghadiyas of 1 h 11 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′. Pushya spans 93°20′–106°40′; the Moon entered its pada 2 at 96°40′. It leaves at 23:58, for Ashlesha.

Add the Sun's and the Moon's places among the stars: 31.3° + 97.5° = 128.8°. The sum, cut into 27 parts of 13°20′, gives the yoga: 120°00′–133°20′ is the 10th, Ganda. It ends at 14:03, then Vriddhi.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Shashthi is Kaulava and the second Taitila. Kaulava ended at 05:20, when the lead reached 66°; Taitila runs until 18:20.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:42 to 05:41 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: Mesha gives Vaishakha. The Sun enters Vrishabha on 14 May, inside the month. The next new moon, 8 Jun, finds it in Vrishabha and begins Jyeshtha.

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 10 May, with the Sun in Mesha, began Vaishakha. This Shukla paksha reads Vaishakha 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 34.7° round the stars. Vikram Samvat numbers that year 2070; Shaka Samvat numbers it 1935.
