Panchang in Progress, Amur Oblast, Russia Thu 16 Aug 2018

Nag Panchami follows the tithi at sunrise. Panchami runs from 06:57 on Wed 15 Aug to 05:21 on Thu 16 Aug, so it holds sunrise only on Thu 16 Aug, at 05:12. No text giving Nag Panchami’s time was found; sunrise is Tithika’s convention.

Nag Panchami: every date in Progress

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 48°–60° is the 5th, Shukla Panchami. A day takes the tithi in force at its sunrise, 05:12 here. Chaturthi ended at 06:57 Wed, before it. Panchami ends at 05:21, when the lead reaches 60°. The lead passed 0° at the new moon of 11 Aug, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Shashthi began at 05:21 and ended at 04:32 Fri, between the sunrises of 05:12 and 05:13 Fri. Thursday reads Panchami and Friday reads Saptami: Shashthi is a kshaya tithi here.

Sunrise here, 05:50, came after Panchami ended at 01:51: this day reads Shashthi.

Progress · UTC+9

Sunrise here, 05:12, came before Panchami ended at 05:21: this day reads Panchami. Shashthi ends at 04:32 Fri, before the next sunrise, so no day here reads Shashthi: it is kshaya.

The night of Wed 15 Aug ran from sunset 19:39 Wed to sunrise 05:12, 9 h 33 m. Cut into 15 muhurtas of 38 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:12 to 19:37, splits into 8 choghadiyas of 1 h 48 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:37 to 05:13 Fri, splits into 8 choghadiyas of 1 h 12 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′. Chitra spans 173°20′–186°40′; the Moon entered its pada 2 at 176°40′. It leaves at 19:18, for Swati.

Add the Sun's and the Moon's places among the stars: 118.8° + 178.8° = 297.6°. The sum, cut into 27 parts of 13°20′, gives the yoga: 293°20′–306°40′ is the 23rd, Shubha. It ends at 20:18, then Shukla.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Panchami is Bava and the second Balava. Bava ended at 18:04 Wed, when the lead reached 54°; Balava runs until 05:21.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:12 to 05:13 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: Karka gives Shravana. The Sun enters Simha on 17 Aug, inside the month. The next new moon, 10 Sep, finds it in Simha and begins Bhadrapada.

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 11 Aug, with the Sun in Karka, began Shravana. This Shukla paksha reads Shravana in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 17 Mar 2018, 22:11 Sat. Since then the Sun has moved 146° round the stars. Vikram Samvat numbers that year 2075; Shaka Samvat numbers it 1940.
