Panchang in Ipameri, Goiás, Brazil Tue 16 Feb 1965

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 180°–192° is the 16th, Krishna Pratipada. A day takes the tithi in force at its sunrise, 07:07 here. Purnima ended at 22:26 Mon, before it. Pratipada ends at 19:23, when the lead reaches 192°. The lead passed 180° at the full moon of 15 Feb, so the Moon is waning: Krishna paksha.

The night of Mon 15 Feb ran from sunset 19:46 Mon to sunrise 07:07, 11 h 21 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:07 to 19:46, splits into 8 choghadiyas of 1 h 34 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:46 to 07:07 Wed, splits into 8 choghadiyas of 1 h 25 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′. Magha spans 120°00′–133°20′; the Moon entered its pada 3 at 126°40′. It leaves at 13:58, for Purva Phalguni.

Add the Sun's and the Moon's places among the stars: 304.1° + 129.1° = 433.2°, one full turn and 73.2°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 66°40′–80°00′ is the 6th, Atiganda. It ends at 17:25, then Sukarma.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Pratipada is Balava and the second Kaulava. Balava runs until 08:52, when the lead reaches 186°; Kaulava until 19:23.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:07 to 07:07 Wed, so the hours after midnight still belong to Mangalawara.

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: Makara gives Magha. The Sun enters Kumbha on 12 Feb, inside the month. The next new moon, 3 Mar, finds it in Kumbha and begins Phalguna.

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 3 Mar, with the Sun in Kumbha, begins Phalguna. Until then this Krishna paksha reads Phalguna here, and Magha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 13 Mar 1964, 23:13 Fri. Since then the Sun has moved 333.9° round the stars. Vikram Samvat numbers that year 2021; Shaka Samvat numbers it 1886.
