Panchang in Chahārbāgh, Alborz Province, Iran Sun 18 Feb 2024

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 108°–120° is the 10th, Shukla Dashami. A day takes the tithi in force at its sunrise, 06:51 here. Navami ended at 06:16, before it. Dashami ends at 06:50 Mon, when the lead reaches 120°. The lead passed 0° at the new moon of 10 Feb, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Dashami began at 06:16, before sunrise at 06:51, and ends at 06:50 Mon, after the next sunrise at 06:50 Mon. Both days read Dashami: it is a vriddhi tithi here.

The night of Sat 17 Feb ran from sunset 17:49 Sat to sunrise 06:51, 13 h 2 m. Cut into 15 muhurtas of 52 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:51 to 17:50, splits into 8 choghadiyas of 1 h 22 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:50 to 06:50 Mon, splits into 8 choghadiyas of 1 h 37 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′. Rohini spans 40°00′–53°20′; the Moon entered its pada 4 at 50°. It leaves at 07:22, for Mrigashira.

Add the Sun's and the Moon's places among the stars: 304.8° + 53.1° = 357.9°. The sum, cut into 27 parts of 13°20′, gives the yoga: 346°40′–360°00′ is the 27th, Vaidhriti. It ends at 10:38, then Vishkambha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dashami is Taitila and the second Garaja. Taitila runs until 18:29, when the lead reaches 114°; Garaja until 06:50 Mon.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:51 to 06:50 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: Makara gives Magha. The Sun enters Kumbha on 13 Feb, inside the month. The next new moon, 10 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 10 Feb, with the Sun in Makara, began Magha. This Shukla paksha reads Magha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 21 Mar 2023, 20:53 Tue. Since then the Sun has moved 328.2° round the stars. Vikram Samvat numbers that year 2080; Shaka Samvat numbers it 1945.
