Panchang in Sevan, Gegharkunik, Armenia Fri 18 Feb 1910

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, 06:51 here. Ashtami ended at 08:43 Thu, before it. Navami ends at 07:22, when the lead reaches 108°. The lead passed 0° at the new moon of 10 Feb, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Dashami began at 07:22 and ended at 06:21 Sat, between the sunrises of 06:51 and 06:49 Sat. Friday reads Navami and Saturday reads Ekadashi: Dashami is a kshaya tithi here.

The night of Thu 17 Feb ran from sunset 17:36 Thu to sunrise 06:51, 13 h 15 m. Cut into 15 muhurtas of 53 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:51 to 17:37, 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, 17:37 to 06:49 Sat, 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′. Mrigashira spans 53°20′–66°40′; the Moon entered its pada 1 at 53°20′. It leaves at 05:44 Sat, for Ardra.

Add the Sun's and the Moon's places among the stars: 306° + 53.8° = 359.8°. The sum, cut into 27 parts of 13°20′, gives the yoga: 346°40′–360°00′ is the 27th, Vaidhriti. It ends at 07:11, then Vishkambha.

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 20:00 Thu, when the lead reached 102°; Kaulava runs until 07:22.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:51 to 06:49 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: Makara gives Magha. The Sun enters Kumbha on 12 Feb, inside the month. The next new moon, 11 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 10 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: 21 Mar 1909, 23:11 Sun. Since then the Sun has moved 328° round the stars. Vikram Samvat numbers that year 1966; Shaka Samvat numbers it 1831.
