Panchang in Pāthardi, Maharashtra Tue 22 May 1990

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 04:34 on Tue 22 May to 01:01 on Wed 23 May, so only Tuesday’s pradosha (18:59–21:09) falls within it. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 01:01 on Wed 23 May to 21:12 on Wed 23 May, between the two nights’ nishitha, touching neither. The Nirnayasindhu then takes the earlier day: Tue 22 May. No text giving Masik Shivratri’s time was found; nishitha is Tithika’s convention.

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 324°–336° is the 28th, Krishna Trayodashi. A day takes the tithi in force at its sunrise, 05:52 here. Dwadashi ended at 04:34, before it. Trayodashi ends at 01:01 Wed, when the lead reaches 336°. The lead passed 180° at the full moon of 10 May, so the Moon is waning: Krishna paksha.

The night of Mon 21 May ran from sunset 18:58 Mon to sunrise 05:52, 10 h 54 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:52 to 18:59, splits into 8 choghadiyas of 1 h 38 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:59 to 05:52 Wed, splits into 8 choghadiyas of 1 h 21 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′. Ashwini spans 0°00′–13°20′; the Moon entered its pada 1 at 0°. It leaves at 00:25 Wed, for Bharani.

Add the Sun's and the Moon's places among the stars: 36.9° + 1.7° = 38.6°. The sum, cut into 27 parts of 13°20′, gives the yoga: 26°40′–40°00′ is the 3rd, Ayushmana. It ends at 07:55, then Saubhagya.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Trayodashi is Garaja and the second Vanija. Garaja runs until 14:50, when the lead reaches 330°; Vanija until 01:01 Wed.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:52 to 05:52 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: Mesha gives Vaishakha. The Sun enters Vrishabha on 15 May, inside the month. The next new moon, 24 May, finds it in Vrishabha and begins Jyeshtha.

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 24 May, with the Sun in Vrishabha, begins Jyeshtha. Until then this Krishna paksha reads Jyeshtha here, and Vaishakha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 27 Mar 1990, 01:18 Tue. Since then the Sun has moved 54.7° round the stars. Vikram Samvat numbers that year 2047; Shaka Samvat numbers it 1912.
