Rahu Kaal Today — Naperville
Thursday, 2026-08-20 · Naperville, Illinois · UTC−5
Rahu Kaal today
14:38 – 16:21
103 minutes · one-eighth of today's 06:08–19:45 day
Note the length: 103 minutes, not a flat 90. Rahu Kaal is an eighth of the real solar day, so it changes with the season and with where you are. This is computed for Naperville's own coordinates with the Swiss Ephemeris.

Why Naperville needs its own figure
Across the year
In Naperville, Rahu Kaal is shortest around the December solstice at 68 minutes and longest around the June solstice at 114 minutes — a spread of 46 minutes, driven entirely by this city's latitude. A table printing a flat 90 is wrong at both ends of the year.
Against the nearest city
Chicago is 46 km away, and today its Rahu Kaal runs 14:36–16:19 against Naperville's 14:38–16:21. Sunrise differs, so the eighth differs. That gap is the reason this page is computed for Naperville rather than for the region.
Frequently asked
What is the Rahu Kaal time today in Naperville?
Today, Thursday, Rahu Kaal in Naperville, Illinois runs 14:38 to 16:21 — 103 minutes. It is computed from today's sunrise (06:08) and sunset (19:45) for this city, so it is not the same as the figure published for a neighbouring metro.
Is Rahu Kaal 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 Naperville today it is 103 minutes. Tables that print a fixed 1.5 hours for every city and every date are approximating.
Does Rahu Kaal fall at the same time every day?
No — the eighth it occupies is set by the weekday, so it moves substantially. That is also why a table memorised for one day is misleading on the next.
What if I have to start something during Rahu Kaal?
Ongoing work is not affected — the caution is about beginnings. If you can move it, the next auspicious choghadiya in Naperville today is Shubh, 06:08–07:50.
Rahu Kaal in other cities
Rahu Kaal is the same for all of Naperville. Your timing is not.
This window comes from the Sun and the weekday, so the whole city shares it. Whether a period is actually good for you depends on your running dasha and the transits over your own chart.
