Panchang in Ipameri, Goiás, Brazil Mon 17 Jul 2017

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 276°–288° is the 24th, Krishna Navami. A day takes the tithi in force at its sunrise, 06:43 here. Ashtami ended at 03:35, before it. Navami ends at 01:30 Tue, when the lead reaches 288°. The lead passed 180° at the full moon of 9 Jul, so the Moon is waning: Krishna paksha.

The night of Sun 16 Jul ran from sunset 17:54 Sun to sunrise 06:43, 12 h 49 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:43 to 17:54, splits into 8 choghadiyas of 1 h 23 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:54 to 06:43 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′. Ashwini spans 0°00′–13°20′; the Moon entered its pada 3 at 6°40′. It leaves at 14:48, for Bharani.

Add the Sun's and the Moon's places among the stars: 90.9° + 8.6° = 99.5°. The sum, cut into 27 parts of 13°20′, gives the yoga: 93°20′–106°40′ is the 8th, Dhriti. It ends at 18:09, then Shula.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Navami is Taitila and the second Garaja. Taitila runs until 14:36, when the lead reaches 282°; Garaja until 01:30 Tue.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:43 to 06:43 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: Mithuna gives Ashadha. The Sun enters Karka on 16 Jul, inside the month. The next new moon, 23 Jul, finds it in Karka and begins Shravana.

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 23 Jul, with the Sun in Karka, begins Shravana. Until then this Krishna paksha reads Shravana here, and Ashadha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 27 Mar 2017, 23:57 Mon. Since then the Sun has moved 107.4° round the stars. Vikram Samvat numbers that year 2074; Shaka Samvat numbers it 1939.
