Panchang in Davinópolis, Maranhão, Brazil Sun 7 Sep 1975

Hartalika Teej’s puja is done in pratahkala, the first fifth of the day. Tritiya runs from 08:39 on Sun 7 Sep to 05:12 on Mon 8 Sep, between the two mornings’ pratahkala, touching neither. The Nirnayasindhu then takes the earlier day: Sun 7 Sep. No text giving Hartalika Teej’s time was found; pratahkala is Tithika’s convention.

Hartalika Teej: every date in Davinópolis

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 12°–24° is the 2nd, Shukla Dwitiya. A day takes the tithi in force at its sunrise, 06:06 here. Pratipada ended at 12:24 Sat, before it. Dwitiya ends at 08:39, when the lead reaches 24°. The lead passed 0° at the new moon of 5 Sep, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Tritiya began at 08:39 and ended at 05:12 Mon, between the sunrises of 06:06 and 06:06 Mon. Sunday reads Dwitiya and Monday reads Chaturthi: Tritiya is a kshaya tithi here.

The night of Sat 6 Sep ran from sunset 18:08 Sat to sunrise 06:06, 11 h 58 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:06 to 18:08, splits into 8 choghadiyas of 1 h 30 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:08 to 06:06 Mon, splits into 8 choghadiyas of 1 h 29 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′. Hasta spans 160°00′–173°20′; the Moon entered its pada 1 at 160°. It leaves at 22:25, for Chitra.

Add the Sun's and the Moon's places among the stars: 140.6° + 163.1° = 303.7°. The sum, cut into 27 parts of 13°20′, gives the yoga: 293°20′–306°40′ is the 23rd, Shubha. It ends at 10:30, then Shukla.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dwitiya is Balava and the second Kaulava. Balava ended at 22:30 Sat, when the lead reached 18°; Kaulava runs until 08:39.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:06 to 06:06 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: Simha gives Bhadrapada. The Sun enters Kanya on 16 Sep, inside the month. The next new moon, 5 Oct, finds it in Kanya and begins Ashwina.

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 5 Sep, with the Sun in Simha, began Bhadrapada. This Shukla paksha reads Bhadrapada in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 11 Apr 1975, 13:38 Fri. Since then the Sun has moved 142.9° round the stars. Vikram Samvat numbers that year 2032; Shaka Samvat numbers it 1897.
