Masik Shivratri: every date in Ipameri

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, 06:10 here. Dwadashi ended at 03:50 Tue, before it. Trayodashi ends at 06:18, when the lead reaches 336°. The lead passed 180° at the full moon of 13 Feb, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Trayodashi began at 03:50 Tue, before sunrise at 06:10 Tue, and ends at 06:18, after the next sunrise at 06:10. Both days read Trayodashi: it is a vriddhi tithi here.

The night of Tue 25 Feb ran from sunset 18:41 Tue to sunrise 06:10, 11 h 29 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:10 to 18:40, 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 night here, 18:40 to 06:11 Thu, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Shravana spans 280°00′–293°20′; the Moon entered its pada 4 at 290°. It leaves at 12:39, for Dhanishtha.

Add the Sun's and the Moon's places among the stars: 314.2° + 290.1° = 604.3°, one full turn and 244.3°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 240°00′–253°20′ is the 19th, Parigha. It ends at 22:55, then Shiva.

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 ended at 17:06 Tue, when the lead reached 330°; Vanija runs until 06:18.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:10 to 06:11 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: Makara gives Magha. The Sun enters Kumbha on 12 Feb, inside the month. The next new moon, 28 Feb, 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 28 Feb, with the Sun in Kumbha, begins Phalguna. Until then this Krishna paksha reads Phalguna here, and Magha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 9 Apr 1929, 17:32 Tue. Since then the Sun has moved 317.6° round the stars. Vikram Samvat numbers that year 1986; Shaka Samvat numbers it 1851.
