Panchang in Thazhecode, Kerala Wed 14 Feb 2018

Chaturdashi touches nishitha on both nights. When it does, the Nirnayasindhu takes the later day: Wed 14 Feb, where it holds nishitha until 00:46 Thu.

Maha Shivratri: every date in Thazhecode

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 336°–348° is the 29th, Krishna Chaturdashi. A day takes the tithi in force at its sunrise, 06:47 here. Trayodashi ended at 22:34 Tue, before it. Chaturdashi ends at 00:46 Thu, when the lead reaches 348°. The lead passed 180° at the full moon of 31 Jan, so the Moon is waning: Krishna paksha.

The night of Tue 13 Feb ran from sunset 18:32 Tue to sunrise 06:47, 12 h 15 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:47 to 18:33, 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 night here, 18:33 to 06:47 Thu, 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 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 1 at 280°. It leaves at 07:30 Thu, for Dhanishtha.

Add the Sun's and the Moon's places among the stars: 301.2° + 280.9° = 582.1°, one full turn and 222.1°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 213°20′–226°40′ is the 17th, Vyatipata. It ends at 15:12, then Variyana.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Vishti and the second Shakuni. Vishti runs until 11:43, when the lead reaches 342°; Shakuni until 00:46 Thu.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:47 to 06:47 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 13 Feb, inside the month. The next new moon, 16 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 16 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: 28 Mar 2017, 08:27 Tue. Since then the Sun has moved 317.7° round the stars. Vikram Samvat numbers that year 2074; Shaka Samvat numbers it 1939.
