Panchang in Myjava, Trenčín Region, Slovakia Sun 15 Aug 2021

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, 05:42 here. Shashthi ended at 08:21 Sat, before it. Saptami ends at 06:21, when the lead reaches 84°. The lead passed 0° at the new moon of 8 Aug, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Ashtami began at 06:21 and ended at 04:15 Mon, between the sunrises of 05:42 and 05:43 Mon. Sunday reads Saptami and Monday reads Navami: Ashtami is a kshaya tithi here.

The night of Sat 14 Aug ran from sunset 20:06 Sat to sunrise 05:42, 9 h 36 m. Cut into 15 muhurtas of 38 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:42 to 20:04, splits into 8 choghadiyas of 1 h 47 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:04 to 05:43 Mon, splits into 8 choghadiyas of 1 h 12 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′. Vishakha spans 200°00′–213°20′; the Moon entered its pada 1 at 200°. It leaves at 00:55 Mon, for Anuradha.

Add the Sun's and the Moon's places among the stars: 118.4° + 202° = 320.4°. The sum, cut into 27 parts of 13°20′, gives the yoga: 320°00′–333°20′ is the 25th, Brahma. It ends at 02:15 Mon, 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 19:22 Sat, when the lead reached 78°; Vanija runs until 06:21.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:42 to 05:43 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: Karka gives Shravana. The Sun enters Simha on 16 Aug, inside the month. The next new moon, 7 Sep, finds it in Simha and begins Bhadrapada.

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 8 Aug, with the Sun in Karka, began Shravana. This Shukla paksha reads Shravana in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 12 Apr 2021, 04:30 Mon. Since then the Sun has moved 120.1° round the stars. Vikram Samvat numbers that year 2078; Shaka Samvat numbers it 1943.
