Panchang in Olean, New York, United States Thu 7 Apr 2016

Ghatasthapana is done in pratahkala, the first fifth of the day. Pratipada runs from 07:23 on Thu 7 Apr to 03:35 on Fri 8 Apr, so it touches only Thursday’s pratahkala (06:45–09:21). No text giving Chaitra Navratri · Ghatasthapana’s time was found; pratahkala is Tithika’s convention.

Chaitra Navratri: every date in Olean

Vikram Samvat 2073 begins with Chaitra Shukla Pratipada. Here Pratipada holds no sunrise, so the year begins on the day it is current: Thu 7 Apr.

Amavasya follows the tithi at sunrise. Amavasya runs from 11:06 on Wed 6 Apr to 07:23 on Thu 7 Apr, so it holds sunrise only on Thu 7 Apr, at 06:45. No text giving Amavasya’s time was found; sunrise is Tithika’s convention.

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 348°–360° is the 30th, Krishna Amavasya. A day takes the tithi in force at its sunrise, 06:45 here. Chaturdashi ended at 11:06 Wed, before it. Amavasya ends at 07:23, when the lead reaches 360°. The lead passed 180° at the full moon of 23 Mar, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Pratipada began at 07:23 and ended at 03:35 Fri, between the sunrises of 06:45 and 06:43 Fri. Thursday reads Amavasya and Friday reads Dwitiya: Pratipada is a kshaya tithi here.

The night of Wed 6 Apr ran from sunset 19:45 Wed to sunrise 06:45, 11 h 0 m. Cut into 15 muhurtas of 44 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:45 to 19:46, 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 night here, 19:46 to 06:43 Fri, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Revati spans 346°40′–360°00′; the Moon entered its pada 3 at 353°20′. It leaves at 16:51, for Ashwini.

Add the Sun's and the Moon's places among the stars: 354° + 353.6° = 707.6°, one full turn and 347.6°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 346°40′–360°00′ is the 27th, Vaidhriti. It ends at 01:10 Fri, then Vishkambha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Amavasya is Chatushpada and the second Nagava. Chatushpada ended at 21:16 Wed, when the lead reached 354°; Nagava runs until 07:23.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:45 to 06:43 Fri, so the hours after midnight still belong to Guruwara.

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: Kumbha gives Phalguna. The Sun enters Meena on 14 Mar, inside the month. The next new moon, 7 Apr, finds it in Meena and begins Chaitra.

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 7 Apr, with the Sun in Meena, begins Chaitra. Until then this Krishna paksha reads Chaitra here, and Phalguna in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 7 Apr 2016, 07:23. Since then the Sun has moved 0° round the stars. Vikram Samvat numbers that year 2073; Shaka Samvat numbers it 1938.
