Panchang in Polatlı, Ankara, Turkey Thu 21 May 2015

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, 05:32 here. Tritiya ended at 03:09, before it. Chaturthi ends at 03:06 Fri, when the lead reaches 48°. The lead passed 0° at the new moon of 18 May, so the Moon is waxing: Shukla paksha.

The night of Wed 20 May ran from sunset 20:03 Wed to sunrise 05:32, 9 h 29 m. Cut into 15 muhurtas of 37 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:32 to 20:04, splits into 8 choghadiyas of 1 h 49 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:04 to 05:32 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′. Ardra spans 66°40′–80°00′; the Moon entered its pada 2 at 70°. It leaves at 18:38, for Punarvasu.

Add the Sun's and the Moon's places among the stars: 35.7° + 72.9° = 108.6°. The sum, cut into 27 parts of 13°20′, gives the yoga: 106°40′–120°00′ is the 9th, Shula. It ends at 01:12 Fri, then Ganda.

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 15:02, when the lead reaches 42°; Vishti until 03:06 Fri.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:32 to 05:32 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: Vrishabha gives Jyeshtha. The Sun enters Mithuna on 15 Jun, inside the month. The next new moon, 16 Jun, finds it in Mithuna and begins Ashadha.

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 18 May, with the Sun in Vrishabha, began Jyeshtha. This Shukla paksha reads Jyeshtha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 20 Mar 2015, 11:36 Fri. Since then the Sun has moved 60.3° round the stars. Vikram Samvat numbers that year 2072; Shaka Samvat numbers it 1937.
