Panchang in Sevan, Gegharkunik, Armenia Fri 14 Sep 2096

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 19:09 on Fri 14 Sep to 18:56 on Sat 15 Sep, so only Friday night’s nishitha (00:32 Sat–01:18 Sat) falls within it. No text giving Masik Shivratri’s time was found; nishitha is Tithika’s convention.

Masik Shivratri: every date in Sevan

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, 06:40 here. Dwadashi ended at 19:46 Thu, before it. Trayodashi ends at 19:09, when the lead reaches 336°. The lead passed 180° at the full moon of 2 Sep, so the Moon is waning: Krishna paksha.

The night of Thu 13 Sep ran from sunset 19:10 Thu to sunrise 06:40, 11 h 30 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:40 to 19:09, 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, 19:09 to 06:41 Sat, 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′. Ashlesha spans 106°40′–120°00′; the Moon entered its pada 4 at 116°40′. It leaves at 12:32, for Magha.

Add the Sun's and the Moon's places among the stars: 147.1° + 116.8° = 263.9°. The sum, cut into 27 parts of 13°20′, gives the yoga: 253°20′–266°40′ is the 20th, Shiva. It ends at 11:20, then Siddha.

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 07:25, when the lead reaches 330°; Vanija until 19:09.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:40 to 06:41 Sat, so the hours after midnight still belong to Shukrawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 18 Aug 07:02 Sat to 16 Sep 19:12 Sun the Sun stayed in Simha, entering Kanya at 17 Sep 05:06 Mon, after the new moon. A month with no sankranti is Adhika Bhadrapada, before Bhadrapada itself.

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 Sep, with the Sun in Simha, begins Bhadrapada (Adhik). Until then this Krishna paksha reads Bhadrapada (Adhik) here, and Bhadrapada (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 24 Mar 2096, 12:56 Sat. Since then the Sun has moved 167.5° round the stars. Vikram Samvat numbers that year 2153; Shaka Samvat numbers it 2018.
