Panchang in Sevan, Gegharkunik, Armenia Sun 15 Feb 1959

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 72°–84° is the 7th, Shukla Saptami. A day takes the tithi in force at its sunrise, 07:54 here. Shashthi ended at 07:21 Sat, before it. Saptami ends at 10:02, when the lead reaches 84°. The lead passed 0° at the new moon of 7 Feb, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Saptami began at 07:21 Sat, before sunrise at 07:56 Sat, and ends at 10:02, after the next sunrise at 07:54. Both days read Saptami: it is a vriddhi tithi here.

The night of Sat 14 Feb ran from sunset 18:32 Sat to sunrise 07:54, 13 h 22 m. Cut into 15 muhurtas of 53 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:54 to 18:34, splits into 8 choghadiyas of 1 h 20 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:34 to 07:53 Mon, splits into 8 choghadiyas of 1 h 39 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′. Bharani spans 13°20′–26°40′; the Moon entered its pada 4 at 23°20′. It leaves at 10:19, for Krittika.

Add the Sun's and the Moon's places among the stars: 302.4° + 25.5° = 327.9°. The sum, cut into 27 parts of 13°20′, gives the yoga: 320°00′–333°20′ is the 25th, Brahma. It ends at 18:02, then Indra.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Saptami is Garaja and the second Vanija. Garaja ended at 20:42 Sat, when the lead reached 78°; Vanija runs until 10:02.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:54 to 07:53 Mon, so the hours after midnight still belong to Raviwara.

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: Makara gives Magha. The Sun enters Kumbha on 12 Feb, inside the month. The next new moon, 9 Mar, finds it in Kumbha and begins Phalguna.

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 7 Feb, with the Sun in Makara, began Magha. This Shukla paksha reads Magha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 20 Mar 1958, 13:49 Thu. Since then the Sun has moved 326.4° round the stars. Vikram Samvat numbers that year 2015; Shaka Samvat numbers it 1880.
