Yamaganda, also spelled Yamagandam, is the third of the three inauspicious daytime windows that a panchang prints beside Rahu Kaal and Gulika Kaal. It is one of the eight equal parts of the day between sunrise and sunset, and which part it takes is fixed by the weekday: the 5th on Sunday, the 4th on Monday, the 3rd on Tuesday, the 2nd on Wednesday, the 1st on Thursday, the 7th on Friday and the 6th on Saturday.
Take the true sunrise and the true sunset for your city on the chosen date, and divide the interval between them into eight equal parts. Yamaganda is the part the weekday assigns: 5th on Sunday, 4th on Monday, 3rd on Tuesday, 2nd on Wednesday, 1st on Thursday, 7th on Friday, 6th on Saturday. Thursday is the only weekday on which it opens the day.
Because the parts are proportional, the window is 90 minutes when the day is twelve hours long and changes with the season. Worked example: sunrise 06:00 and sunset 18:00 on a Thursday puts Yamaganda at 06:00 to 07:30, the very first part. The same day-length on a Friday moves it to the 7th part, 15:00 to 16:30.
The tradition attaches a specific flavour to this window that separates it from the other two. Activities begun during Yamaganda are said not to reach completion, so the objection is to inception rather than to activity as such, and work already under way is not usually stopped for it.
That is a statement of what the electional tradition holds, not a prediction this calculator makes about you. Yamaganda is a property of the date and the place, identical for everyone in the same city on the same day, and no part of it is read from a birth chart.
The same eight-part division of daylight carries all three of the day-doshas. Rahu Kaal takes the 8th part on Sunday, the 2nd on Monday, the 7th on Tuesday, the 5th on Wednesday, the 6th on Thursday, the 4th on Friday and the 3rd on Saturday. Gulika Kaal runs down from the 7th part on Sunday to the 1st on Saturday. Yamaganda takes the third distinct part, so a day always carries three separate windows.
None of the three has an attested parihara in the electional texts this app follows, which is why they are handled as absolute exclusions for an auspicious inception rather than as periods to be neutralised. Dur-Muhurtam, computed from the fifteen diurnal muhurtas rather than from the eight parts, adds one or two more windows on most weekdays.
Yamaganda is associated with obstacles to completion. Tasks started in this window are traditionally said to face delays or to fail to reach their goal, so new undertakings are postponed past it, while work already in progress is not usually interrupted for it.
Divide sunrise to sunset into eight equal parts. Yamaganda is the 5th part on Sunday, the 4th on Monday, the 3rd on Tuesday, the 2nd on Wednesday, the 1st on Thursday, the 7th on Friday and the 6th on Saturday. Thursday is the only day on which it is the first part after sunrise.
One eighth of the interval between sunrise and sunset. That is 90 minutes on a twelve-hour day, and proportionally shorter or longer as daylight changes with the season and your latitude.
They are treated as separate exclusion windows rather than ranked on one scale. Rahu Kaal is the most widely observed of the three day-doshas, Gulika is usually described as the mildest, and Yamaganda carries the specific sense of work that does not reach completion.
No. It is computed from the weekday and from your city's sunrise and sunset only. Everyone in the same city has the same Yamaganda window on the same date, whatever their horoscope.
