The four windows people confuse
Three inauspicious, one auspicious. All four are eighths of today's solar arc in Boston.
Rahu Kalam
Rahu
8:19 AM – 9:43 AM
The window to avoid beginning anything new — travel, signing, buying, a first meeting.
Yamagandam
Ketu
11:07 AM – 12:31 PM
Also avoided for new beginnings, and routinely mistaken for Rahu Kaal.
Gulika Kalam
Saturn
1:55 PM – 3:19 PM
Saturn's eighth. Traditionally avoided, though held to be the mildest of the three.
Abhijit Muhurat
Brahma
12:09 PM – 12:54 PM
The opposite: the midday window held to be auspicious for almost anything.

Ekadashi, Purnima and Amavasya in Boston
By the sunrise rule most panchangs use, 4 of these 4 fall on a different calendar day in Boston than in New Delhi: the two sunrises meet the tithi on different days. Sectarian refinements are not applied.

When Boston's clocks change
Boston moves from UTC−4 to UTC−5 on November 1, 2026. The Sun does not change, so Rahu Kaal stays the same eighth of the day, but its clock time jumps: on November 1, 2026 it runs 3:20 PM–4:37 PM on the new clock, which would have read 4:20 PM–5:37 PM on the old one. Anything you scheduled by the clock moves with it.
Why Boston needs its own figure
Across the year
In Boston, Rahu Kaal is shortest at 68 minutes and longest at 114 minutes across the year, a spread of 46 minutes set by this city's latitude.
Against the nearest city
New York is 190 miles away, and today its Rahu Kaal runs 8:30 AM–9:54 AM against Boston's 8:19 AM–9:43 AM. Sunrise differs, so the eighth differs. That gap is the reason this page is computed for Boston rather than for the region.
Frequently asked
What is the Rahu Kalam time today in Boston?
Today, Monday, Rahu Kalam in Boston, Massachusetts runs 8:19 AM to 9:43 AM — 84 minutes. It is computed from today's sunrise (6:55 AM) and sunset (6:07 PM) in Boston.
Is Rahu Kalam the same as Rahu Kaal?
Yes — one window, two transliterations of the same Sanskrit कालः. "Rahu Kalam" is the usual South Indian form (Tamil ராகு காலம், Telugu రాహు కాలం) and "Rahu Kaal" the North Indian one. The same page names Yamagandam and Gulika Kalam, which are written Yamaganda and Gulika Kaal in the north. Nothing about the calculation changes with the spelling.
Is Rahu Kalam always 90 minutes?
No. It is one-eighth of the interval between sunrise and sunset, so it is only 90 minutes when the day is exactly twelve hours long. In Boston today it is 84 minutes.
Does Rahu Kalam fall at the same time every day?
No. The weekday decides which eighth it takes: this week in Boston it starts as early as 8:19 AM on Monday and as late as 4:44 PM on Sunday.
When is the next Ekadashi in Boston?
By the sunrise rule most panchangs follow, Papankusha Ekadashi falls on Wednesday, October 21, 2026 in Boston; in New Delhi it is Thursday, October 22, 2026, because the two sunrises meet the tithi on different days.
Does Rahu Kalam change when the clocks change in Boston?
Boston moves from UTC−4 to UTC−5 on November 1, 2026. The Sun does not change, so Rahu Kaal stays the same eighth of the day, but its clock time jumps: on November 1, 2026 it runs 3:20 PM–4:37 PM on the new clock, which would have read 4:20 PM–5:37 PM on the old one. Anything you scheduled by the clock moves with it.
What if I have to start something during Rahu Kalam?
Ongoing work is not affected — the caution is about beginnings. If you can move it, the next auspicious choghadiya in Boston today is Amrit, 6:55 AM–8:19 AM.
Rahu Kalam in other cities
Boston shares this. Your chart does not.
These windows come from the Sun and the weekday, so a whole city shares them. Whether a period is actually good for you depends on your own running dasha and the transits over your chart.
