Panchang in Sevan, Gegharkunik, Armenia Fri 18 Jan 1918

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 60°–72° is the 6th, Shukla Shashthi. A day takes the tithi in force at its sunrise, 07:20 here. Panchami ended at 11:08 Thu, before it. Shashthi ends at 08:38, when the lead reaches 72°. The lead passed 0° at the new moon of 13 Jan, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Saptami began at 08:38 and ended at 06:31 Sat, between the sunrises of 07:20 and 07:20 Sat. Friday reads Shashthi and Saturday reads Ashtami: Saptami is a kshaya tithi here.

The night of Thu 17 Jan ran from sunset 16:59 Thu to sunrise 07:20, 14 h 21 m. Cut into 15 muhurtas of 57 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:20 to 17:00, 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 night here, 17:00 to 07:20 Sat, splits into 8 choghadiyas of 1 h 47 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 Bhadrapada spans 333°20′–346°40′; the Moon entered its pada 4 at 343°20′. It leaves at 08:42, for Revati.

Add the Sun's and the Moon's places among the stars: 274.6° + 345.9° = 620.5°, one full turn and 260.5°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 253°20′–266°40′ is the 20th, Shiva. It ends at 17:09, then Siddha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Shashthi is Kaulava and the second Taitila. Kaulava ended at 21:50 Thu, when the lead reached 66°; Taitila runs until 08:38.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:20 to 07:20 Sat, so the hours after midnight still belong to Shukrawara.

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: Dhanu gives Pausha. The Sun enters Makara on 13 Jan, inside the month. The next new moon, 11 Feb, finds it in Makara and begins Magha.

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 13 Jan, with the Sun in Dhanu, began Pausha. This Shukla paksha reads Pausha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 23 Mar 1917, 07:04 Fri. Since then the Sun has moved 295.3° round the stars. Vikram Samvat numbers that year 1974; Shaka Samvat numbers it 1839.
