Panchang in Codcod, Western Visayas, Philippines Tue 16 Mar 2010

Ghatasthapana is done in pratahkala, the first fifth of the day. Pratipada began at 05:01 on Tue 16 Mar, before that morning’s pratahkala, and ended at 06:37 on Wed 17 Mar, partway into the next. The Nirnayasindhu takes the morning Pratipada fills: Tue 16 Mar. No text giving Chaitra Navratri · Ghatasthapana’s time was found; pratahkala is Tithika’s convention.

Chaitra Navratri: every date in Codcod

Vikram Samvat 2067 begins on the day Chaitra Shukla Pratipada holds sunrise: Tue 16 Mar, at 05:54. Pratipada lasts until 06:37 Wed.

Nav Samvatsar: every date in Codcod

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 0°–12° is the 1st, Shukla Pratipada. A day takes the tithi in force at its sunrise, 05:54 here. Amavasya ended at 05:01, before it. Pratipada ends at 06:37 Wed, when the lead reaches 12°. The lead passed 0° at the new moon of 16 Mar, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Pratipada began at 05:01, before sunrise at 05:54, and ends at 06:37 Wed, after the next sunrise at 05:53 Wed. Both days read Pratipada: it is a vriddhi tithi here.

The night of Mon 15 Mar ran from sunset 17:58 Mon to sunrise 05:54, 11 h 56 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:54 to 17:58, splits into 8 choghadiyas of 1 h 30 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:58 to 05:53 Wed, splits into 8 choghadiyas of 1 h 29 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′. Purva Bhadrapada spans 320°00′–333°20′; the Moon entered its pada 4 at 330°. It leaves at 09:17, for Uttara Bhadrapada.

Add the Sun's and the Moon's places among the stars: 331.2° + 331.6° = 662.8°, one full turn and 302.8°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 293°20′–306°40′ is the 23rd, Shubha. It ends at 12:55, then Shukla.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Pratipada is Kinstughna and the second Bava. Kinstughna runs until 17:52, when the lead reaches 6°; Bava until 06:37 Wed.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:54 to 05:53 Wed, so the hours after midnight still belong to Mangalawara.

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: Meena gives Chaitra. The Sun enters Mesha on 14 Apr, inside the month. The next new moon, 14 Apr, finds it in Mesha and begins Vaishakha.

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 16 Mar, with the Sun in Meena, began Chaitra. This Shukla paksha reads Chaitra in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 16 Mar 2010, 05:01. Since then the Sun has moved 0° round the stars. Vikram Samvat numbers that year 2067; Shaka Samvat numbers it 1932.
