Panchang in Sevan, Gegharkunik, Armenia Sun 28 Apr 2075

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 05:39 on Sun 28 Apr to 03:52 on Mon 29 Apr, so only Sunday’s pradosha (19:52–21:54) falls within it. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 144°–156° is the 13th, Shukla Trayodashi. A day takes the tithi in force at its sunrise, 06:03 here. Dwadashi ended at 05:39, before it. Trayodashi ends at 03:52 Mon, when the lead reaches 156°. The lead passed 0° at the new moon of 15 Apr, so the Moon is waxing: Shukla paksha.

Sunrise here, 05:43, came before Dwadashi ended at 07:09: this day reads Dwadashi. Trayodashi ends at 05:22 Mon, before the next sunrise, so no day here reads Trayodashi: it is kshaya.

The night of Sat 27 Apr ran from sunset 19:51 Sat to sunrise 06:03, 10 h 12 m. Cut into 15 muhurtas of 40 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:03 to 19:52, splits into 8 choghadiyas of 1 h 43 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:52 to 06:01 Mon, splits into 8 choghadiyas of 1 h 16 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′. Uttara Phalguni spans 146°40′–160°00′; the Moon entered its pada 4 at 156°40′. It leaves at 10:49, for Hasta.

Add the Sun's and the Moon's places among the stars: 13° + 157.3° = 170.3°. The sum, cut into 27 parts of 13°20′, gives the yoga: 160°00′–173°20′ is the 13th, Vyaghata. It ends at 10:58, then Harshana.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Trayodashi is Kaulava and the second Taitila. Kaulava runs until 16:51, when the lead reaches 150°; Taitila until 03:52 Mon.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:03 to 06:01 Mon, so the hours after midnight still belong to Raviwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 15 Apr 12:56 Mon to 15 May 03:23 Wed the Sun stayed in Mesha, entering Vrishabha at 15 May 18:09 Wed, after the new moon. A month with no sankranti is Adhika Vaishakha, before Vaishakha 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 15 Apr, with the Sun in Mesha, began Vaishakha (Adhik). This Shukla paksha reads Vaishakha (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 16 Mar 2075, 23:26 Sat. Since then the Sun has moved 41.6° round the stars. Vikram Samvat numbers that year 2132; Shaka Samvat numbers it 1997.
