Panchang in Dhing, Assam Fri 7 Jul 2017

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 144°–156° is the 13th, Shukla Trayodashi. A day takes the tithi in force at its sunrise, 04:32 here. Dwadashi ended at 02:52 Thu, before it. Trayodashi ends at 05:14, when the lead reaches 156°. The lead passed 0° at the new moon of 24 Jun, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Trayodashi began at 02:52 Thu, before sunrise at 04:32 Thu, and ends at 05:14, after the next sunrise at 04:32. Both days read Trayodashi: it is a vriddhi tithi here.

The night of Thu 6 Jul ran from sunset 18:16 Thu to sunrise 04:32, 10 h 16 m. Cut into 15 muhurtas of 41 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 04:32 to 18:16, splits into 8 choghadiyas of 1 h 43 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:16 to 04:33 Sat, splits into 8 choghadiyas of 1 h 17 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′. Jyeshtha spans 226°40′–240°00′; the Moon entered its pada 3 at 233°20′. It leaves at 11:21, for Mula.

Add the Sun's and the Moon's places among the stars: 80.9° + 236.6° = 317.5°. The sum, cut into 27 parts of 13°20′, gives the yoga: 306°40′–320°00′ is the 24th, Shukla. It ends at 09:04, then Brahma.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Trayodashi is Kaulava and the second Taitila. Kaulava ended at 16:03 Thu, when the lead reached 150°; Taitila runs until 05:14.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 04:32 to 04:33 Sat, so the hours after midnight still belong to Shukrawara.

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: Mithuna gives Ashadha. The Sun enters Karka on 16 Jul, inside the month. The next new moon, 23 Jul, finds it in Karka and begins Shravana.

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 24 Jun, with the Sun in Mithuna, began Ashadha. This Shukla paksha reads Ashadha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 28 Mar 2017, 08:27 Tue. Since then the Sun has moved 97.4° round the stars. Vikram Samvat numbers that year 2074; Shaka Samvat numbers it 1939.
