Panchang in Chahārbāgh, Alborz Province, Iran Wed 10 Oct 2018

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, 06:08 here. Pratipada ended at 05:25, before it. Dwitiya ends at 04:06 Thu, when the lead reaches 24°. The lead passed 0° at the new moon of 9 Oct, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise.

Sunrise here, 06:18, came before Pratipada ended at 07:25: this day reads Pratipada. Dwitiya ends at 06:06 Thu, before the next sunrise, so no day here reads Dwitiya: it is kshaya.

Sunrise here, 06:08, came after Pratipada ended at 05:25: this day reads Dwitiya.

The night of Tue 9 Oct ran from sunset 17:39 Tue to sunrise 06:08, 12 h 29 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:08 to 17:38, splits into 8 choghadiyas of 1 h 26 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:38 to 06:09 Thu, splits into 8 choghadiyas of 1 h 33 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 4 at 183°20′. It leaves at 09:00, for Swati.

Add the Sun's and the Moon's places among the stars: 172.6° + 185° = 357.6°. The sum, cut into 27 parts of 13°20′, gives the yoga: 346°40′–360°00′ is the 27th, Vaidhriti. It ends at 09:57, then Vishkambha.

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 runs until 16:41, when the lead reaches 18°; Kaulava until 04:06 Thu.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:08 to 06:09 Thu, so the hours after midnight still belong to Budhawara.

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: Kanya gives Ashwina. The Sun enters Tula on 17 Oct, inside the month. The next new moon, 7 Nov, finds it in Tula and begins Kartika.

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 9 Oct, with the Sun in Kanya, began Ashwina. This Shukla paksha reads Ashwina in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 17 Mar 2018, 16:41 Sat. Since then the Sun has moved 199.8° round the stars. Vikram Samvat numbers that year 2075; Shaka Samvat numbers it 1940.
