Panchang in Ipameri, Goiás, Brazil Sun 18 Apr 1926

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 72°–84° is the 7th, Shukla Saptami. A day takes the tithi in force at its sunrise, 06:22 here. Shashthi ended at 05:25, before it. Saptami ends at 07:15 Mon, when the lead reaches 84°. The lead passed 0° at the new moon of 12 Apr, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Saptami began at 05:25, before sunrise at 06:22, and ends at 07:15 Mon, after the next sunrise at 06:22 Mon. Both days read Saptami: it is a vriddhi tithi here.

The night of Sat 17 Apr ran from sunset 18:02 Sat to sunrise 06:22, 12 h 20 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:22 to 18:01, splits into 8 choghadiyas of 1 h 27 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:01 to 06:22 Mon, splits into 8 choghadiyas of 1 h 32 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 4 at 76°40′. It leaves at 11:51, for Punarvasu.

Add the Sun's and the Moon's places among the stars: 4.8° + 77.2° = 82°. The sum, cut into 27 parts of 13°20′, gives the yoga: 80°00′–93°20′ is the 7th, Sukarma. It ends at 03:09 Mon, then Dhriti.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Saptami is Garaja and the second Vanija. Garaja runs until 18:16, when the lead reaches 78°; Vanija until 07:15 Mon.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:22 to 06:22 Mon, so the hours after midnight still belong to Raviwara.

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: Meena gives Chaitra. The Sun enters Mesha on 13 Apr, inside the month. The next new moon, 11 May, finds it in Mesha and begins Vaishakha.

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 12 Apr, with the Sun in Meena, began Chaitra. This Shukla paksha reads Chaitra in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 12 Apr 1926, 09:56 Mon. Since then the Sun has moved 5.8° round the stars. Vikram Samvat numbers that year 1983; Shaka Samvat numbers it 1848.
