Ravi Yoga 2026-2027: Dates and Times, Month by Month

Ravi Yoga is read off two nakshatras, not one. Count from the nakshatra the Sun occupies, calling it the first, to the nakshatra the Moon occupies: when the count is the 4th, 6th, 9th, 10th, 13th and 20th, almanacs mark Ravi Yoga, and it lasts until either body changes nakshatra. From 1 November 2026 to the end of 2027 that happens 87 times, about six a month, counting one already in progress when November opens. November 2026’s first new window opens at 12 November, 14:18.

How the Count Works

The count is inclusive. If the Sun is in Vishakha, the first, then Anuradha is the second, Jyeshtha the third, and Moola, the fourth, is a Ravi Yoga nakshatra for as long as the Sun stays in Vishakha. Six of the twenty-seven counts qualify, so over a long run Ravi Yoga should hold for about six parts in twenty-seven, or 22% of the time; the measured share over this range is 22%. Despite the word yoga it is not one of the 27 yogas in a panchang’s yoga column, which are the Sun’s and Moon’s longitudes added together. It is also not tied to the weekday, so unlike Sarvartha Siddhi it has no sunrise question: each window simply starts and ends at a sky instant.

The Sun spends between 13 and 14 days in each nakshatra, and the Moon about a day, so almost every window opens and closes with the Moon. Not all of them do. Eight windows open at the moment the Sun moves into a new nakshatra, which shifts the whole count by one and turns the Moon’s current nakshatra into a qualifying one; seven close the same way. The Sun’s entry into Ashwini at 15:23 on 14 April 2027, the same instant as its entry into sidereal Aries, ends a Ravi Yoga that began at 10:52 that morning. The shortest window of the range, 2 h 10 min on 8 June 2027, opens on a Sun change and closes on a Moon change.

Because 9 and 10 sit next to each other in the list, the Moon can pass from a 9th into a 10th nakshatra without a break, and fourteen windows below are joined runs of that kind. The longest runs from 04:34 on 18 November 2026 to 06:50 on 21 November, 74 h 16 min in all: the Sun moves from Vishakha into Anuradha at 03:00 on 20 November, in the middle of it, so the Moon’s nakshatra drops from the 10th back to the 9th and the yoga carries on through a second 9th-10th pair.

Where the Times Come From

The Sun and Moon positions are from the JPL DE421 ephemeris with the Lahiri ayanamsa, and the nakshatra boundaries are cut to the minute in IST. They are the same moment everywhere in India, so these times need no city adjustment. Two checks run before the list is built: the Moon spans reproduced all 866 sunrise tithi and nakshatra values of the site’s daily panchang, and the Sun’s entries into Ashwini, Magha and Moola match, to the minute, the four Mesha, Simha and Dhanu sankrantis in the range from the site’s solar ingress tables.

What Almanacs Use It For

The name means the Sun’s yoga, and the almanacs that print it treat it as a favourable window for beginning ordinary work; some also describe it as setting aside other unfavourable combinations of the same hours. That is a ranking inside the custom, which this page reports and cannot test. A Ravi Yoga does not make a muhurat on its own: the muhurat pages check the tithi, the panchang yoga, the weekday and each occasion’s nakshatra list, and no window here says anything about how a thing begun in it will turn out.

The Sun’s month-by-month movement through the signs is on the 2027 Sun transit page, and the counting of nakshatras from a starting star, the same inclusive count used here, is the basis of Tara Bala.
