Panchang in Sevan, Gegharkunik, Armenia Mon 14 Oct 2002

Maha Navami follows the tithi at sunrise. Navami runs from 22:42 on Sun 13 Oct to 23:30 on Mon 14 Oct, so it holds sunrise only on Mon 14 Oct, at 08:09. No text giving Maha Navami’s time was found; sunrise is Tithika’s convention.

Maha Navami: every date in Sevan

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, 08:09 here. Ashtami ended at 22:42 Sun, before it. Navami ends at 23:30, when the lead reaches 108°. The lead passed 0° at the new moon of 6 Oct, so the Moon is waxing: Shukla paksha.

The night of Sun 13 Oct ran from sunset 19:23 Sun to sunrise 08:09, 12 h 46 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 08:09 to 19:22, splits into 8 choghadiyas of 1 h 24 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:22 to 08:10 Tue, splits into 8 choghadiyas of 1 h 36 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 Ashadha spans 266°40′–280°00′; the Moon entered its pada 4 at 276°40′. It leaves at 13:15, for Shravana.

Add the Sun's and the Moon's places among the stars: 176.7° + 277.3° = 454°, one full turn and 94°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 93°20′–106°40′ is the 8th, Dhriti. It ends at 06:37 Tue, then Shula.

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 runs until 11:01, when the lead reaches 102°; Kaulava until 23:30.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:09 to 08:10 Tue, so the hours after midnight still belong to Somawara.

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: Kanya gives Ashwina. The Sun enters Tula on 17 Oct, inside the month. The next new moon, 5 Nov, finds it in Tula and begins Kartika.

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 6 Oct, with the Sun in Kanya, began Ashwina. This Shukla paksha reads Ashwina in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 13 Apr 2002, 00:21 Sat. Since then the Sun has moved 177.9° round the stars. Vikram Samvat numbers that year 2059; Shaka Samvat numbers it 1924.
