Find the auspicious days and times for any day, week or month — good times to begin new work, plus the Rahu Kalaya, Yamaganda and Gulika periods to avoid.
Subha dawas (auspicious days) and subha welawan (auspicious times) are the moments the traditional Sri Lankan almanac considers favourable for starting new work. Each day is judged by the Moon's nakshatra and the tithi (lunar day), while the best hours are found by setting aside the three inauspicious periods of the day — Rahu Kalaya, Yamaganda and Gulika. This page calculates all of these automatically for whichever day, week or month you choose.
Everything on this page is computed automatically from astronomical data — the same engine behind our horoscope readings. For your selected location we divide the daylight (sunrise to sunset) into eight equal parts and mark the traditional inauspicious parts:
People most often look for a subha nekatha before life's big steps. The good times shown above apply generally to starting these activities; for a decision tied to your own horoscope, order a personalised Nakatha.
Starting to build a house, laying the foundation, or beginning work on an upper floor (උඩ මහල) are traditionally begun at a subha nekatha on a favourable day, avoiding the Rahu Kalaya.
Opening a shop, signing agreements or starting a new venture are begun during an auspicious window on a favourable nakshatra day.
Setting off on an important journey is timed to a good period and direction, keeping clear of the inauspicious hours.
Entering a new home (ගෘහ ප්රවේශය) is done at an auspicious time on a day with a favourable tithi and nakshatra.
Choose the Month view above to see every day of the current month marked as favourable, mixed or best avoided, based on its nakshatra and tithi. Tap any day to see its auspicious hours and the Rahu Kalaya, Yamaganda and Gulika periods to avoid.
A subha nekatha is a favourable window of time for beginning something important. It is chosen by combining the day's lunar factors with the hours that fall outside the three inauspicious periods of the day.
Work on an upper floor is traditionally started on a favourable day (a good nakshatra and tithi) during an auspicious hour, avoiding the Rahu Kalaya. Use the calendar above to find such days this month, and consider a personalised Nakatha that also accounts for the house owner's horoscope.
They are three inauspicious periods of each day. The daylight is split into eight equal parts and, for each weekday, one part is Rahu Kalaya, one Yamaganda and one Gulika. New work is not begun during these windows.
Yes. Choose your country from the Location selector and the sunrise, sunset and inauspicious periods are recalculated for that timezone. The nakshatra and tithi are the same worldwide because they depend on the Moon's position.
Sunrise, sunset and the derived periods use precise astronomical calculations. Nakshatra and tithi come from the Moon's and Sun's positions via Swiss Ephemeris, the same source used for our horoscope reports.
No. The favourable/mixed/avoid rating is a general almanac guide based on the day's nakshatra and tithi. A truly personalised auspicious time must consider your own birth chart — that is what our Nakatha service provides.
A nakshatra is one of 27 lunar mansions the Moon passes through; a tithi is the lunar day set by the angle between the Moon and Sun. Together they shape whether a day is considered auspicious.
Rikta tithis (the 4th, 9th and 14th of each fortnight) and the new moon (amavasya) are traditionally considered weak for beginning new work, so the day-quality rating treats them with caution.
This page is a helpful general guide. For an important event tied to a specific person — a wedding, house-warming or business launch — a personalised Nakatha prepared from the horoscope is recommended.
