Panchang in Ipameri, Goiás, Brazil Mon 14 Feb 1910

Saraswati Puja is done in purvahna, the first half of the day. Panchami runs from 11:22 on Sun 13 Feb to 08:45 on Mon 14 Feb, touching purvahna on both mornings. The Nirnayasindhu takes the morning it holds more of: Mon 14 Feb. No text giving Vasant Panchami’s time was found; purvahna is Tithika’s convention.

Vasant Panchami: every date in Ipameri

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 48°–60° is the 5th, Shukla Panchami. A day takes the tithi in force at its sunrise, 06:06 here. Chaturthi ended at 11:28 Sun, before it. Panchami ends at 08:51, when the lead reaches 60°. The lead passed 0° at the new moon of 9 Feb, so the Moon is waxing: Shukla paksha.

The night of Sun 13 Feb ran from sunset 18:48 Sun to sunrise 06:06, 11 h 18 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:06 to 18:47, splits into 8 choghadiyas of 1 h 35 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:47 to 06:06 Tue, 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 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 1 at 0°. It leaves at 03:16 Tue, for Bharani.

Add the Sun's and the Moon's places among the stars: 302.2° + 0.7° = 302.9°. The sum, cut into 27 parts of 13°20′, gives the yoga: 293°20′–306°40′ is the 23rd, Shubha. It ends at 11:58, then Shukla.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Panchami is Bava and the second Balava. Bava ended at 22:08 Sun, when the lead reached 54°; Balava runs until 08:51.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:06 to 06:06 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: Makara gives Magha. The Sun enters Kumbha on 12 Feb, inside the month. The next new moon, 11 Mar, finds it in Kumbha and begins Phalguna.

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 Feb, with the Sun in Makara, began Magha. This Shukla paksha reads Magha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 21 Mar 1909, 17:11 Sun. Since then the Sun has moved 324.2° round the stars. Vikram Samvat numbers that year 1966; Shaka Samvat numbers it 1831.
