Panchang in Ipameri, Goiás, Brazil Mon 15 Oct 2018

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, 05:44 here. Shashthi ended at 23:35 Sun, before it. Saptami ends at 01:46 Tue, when the lead reaches 84°. The lead passed 0° at the new moon of 9 Oct, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise.

The night of Sun 14 Oct ran from sunset 18:13 Sun to sunrise 05:44, 11 h 31 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:44 to 18:13, splits into 8 choghadiyas of 1 h 33 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:13 to 05:43 Tue, splits into 8 choghadiyas of 1 h 26 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′. Mula spans 240°00′–253°20′; the Moon entered its pada 4 at 250°. It leaves at 07:03, for Purva Ashadha.

Add the Sun's and the Moon's places among the stars: 177.8° + 252.7° = 430.5°, one full turn and 70.5°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 66°40′–80°00′ is the 6th, Atiganda. It ends at 23:19, then Sukarma.

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 runs until 12:37, when the lead reaches 78°; Vanija until 01:46 Tue.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:44 to 05:43 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: Kanya gives Ashwina. The Sun enters Tula on 17 Oct, inside the month. The next new moon, 7 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 9 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: 17 Mar 2018, 10:11 Sat. Since then the Sun has moved 205° round the stars. Vikram Samvat numbers that year 2075; Shaka Samvat numbers it 1940.
