Panchang in Diffa, Niger Tue 18 Sep 2012

Hartalika Teej’s puja is done in pratahkala, the first fifth of the day. Tritiya runs from 22:10 on Mon 17 Sep to 19:27 on Tue 18 Sep, so only Tuesday’s pratahkala (05:58–08:24) falls within it. No text giving Hartalika Teej’s time was found; pratahkala is Tithika’s convention.

Hartalika Teej: every date in Diffa

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 24°–36° is the 3rd, Shukla Tritiya. A day takes the tithi in force at its sunrise, 05:58 here. Dwitiya ended at 22:10 Mon, before it. Tritiya ends at 19:27, when the lead reaches 36°. The lead passed 0° at the new moon of 16 Sep, so the Moon is waxing: Shukla paksha.

The night of Mon 17 Sep ran from sunset 18:09 Mon to sunrise 05:58, 11 h 49 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:58 to 18:08, splits into 8 choghadiyas of 1 h 31 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 05:58 Wed, splits into 8 choghadiyas of 1 h 28 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′. Chitra spans 173°20′–186°40′; the Moon entered its pada 3 at 180°. It leaves at 16:55, for Swati.

Add the Sun's and the Moon's places among the stars: 151.7° + 180° = 331.7°. The sum, cut into 27 parts of 13°20′, gives the yoga: 320°00′–333°20′ is the 25th, Brahma. It ends at 08:31, then Indra.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Tritiya is Taitila and the second Garaja. Taitila runs until 08:49, when the lead reaches 30°; Garaja until 19:27.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:58 to 05:58 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: Simha gives Bhadrapada. The Sun enters Kanya on 16 Sep, inside the month. The next new moon, 15 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 16 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: 22 Mar 2012, 15:37 Thu. Since then the Sun has moved 173.4° round the stars. Vikram Samvat numbers that year 2069; Shaka Samvat numbers it 1934.
