Panchang in Sevan, Gegharkunik, Armenia Tue 27 Jul 1909

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 96°–108° is the 9th, Shukla Navami. A day takes the tithi in force at its sunrise, 04:51 here. Ashtami ended at 03:45 Mon, before it. Navami ends at 05:23, when the lead reaches 108°. The lead passed 0° at the new moon of 17 Jul, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Navami began at 03:45 Mon, before sunrise at 04:50 Mon, and ends at 05:23, after the next sunrise at 04:51. Both days read Navami: it is a vriddhi tithi here.

The night of Mon 26 Jul ran from sunset 19:21 Mon to sunrise 04:51, 9 h 30 m. Cut into 15 muhurtas of 38 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 04:51 to 19:20, 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, 19:20 to 04:52 Wed, splits into 8 choghadiyas of 1 h 11 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′. Vishakha spans 200°00′–213°20′; the Moon entered its pada 3 at 206°40′. It leaves at 14:09, for Anuradha.

Add the Sun's and the Moon's places among the stars: 100.8° + 208.5° = 309.3°. The sum, cut into 27 parts of 13°20′, gives the yoga: 306°40′–320°00′ is the 24th, Shukla. It ends at 23:59, then Brahma.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Navami is Balava and the second Kaulava. Balava ended at 16:38 Mon, when the lead reached 102°; Kaulava runs until 05:23.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 04:51 to 04:52 Wed, so the hours after midnight still belong to Mangalawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 17 Jul 13:44 Sat to 16 Aug 02:54 Mon the Sun stayed in Karka, entering Simha at 16 Aug 06:05 Mon, after the new moon. A month with no sankranti is Adhika Shravana, before Shravana 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 17 Jul, with the Sun in Karka, began Shravana (Adhik). This Shukla paksha reads Shravana (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 21 Mar 1909, 23:11 Sun. Since then the Sun has moved 122.8° round the stars. Vikram Samvat numbers that year 1966; Shaka Samvat numbers it 1831.
