sunnah fast again
A warm, no-pressure reminder lands the evening before every recommended fasting day — Monday, a White Day, Arafah — right at 7 PM your local time, Insha Allah.
The days we’ll nudge you for
Every week. “The deeds are presented on Monday and Thursday, and I like that my deeds be presented while I am fasting.” — Sunan al-Tirmidhi 747
The three bright-moon days each month. “Fasting three days of every month is like fasting for a lifetime.” — Bukhari 1979 / Muslim 1159
The 9th & 10th of Muharram. “Fasting the Day of Ashura, I hope, expiates for the year that came before it.” — Sahih Muslim 1162
The best ten days; Arafah greatest of all. “Fasting the Day of Arafah… expiates for the year before it and the year after it.” — Sahih Muslim 1162
After Ramadan. “Whoever fasts Ramadan and follows it with six days of Shawwal, it is as if he fasted for a lifetime.” — Sahih Muslim 1164
Not a fast — a Thursday-evening note for Friday: Surah al-Kahf, salawat and the hour of acceptance. “Whoever recites Surah al-Kahf on the day of Jumuah, a light will shine for him between the two Fridays.” — al-Hakim / al-Bayhaqi (sahih, Sahih al-Jami’ 6470)
Silent all of Ramadan, and never a nudge on the two Eids or the days of Tashreeq. Just the good days.

Honest questions
Which calendar do you use?
A tabular (arithmetic) Islamic calendar, anchored to India (13 July 2026 = 27 Muharram 1448). It’s computed on our server — no external API — so it’s fast and private.
My country’s moon sighting is a day off. Can I fix that?
Yes. The ±1 “sync” adjuster shifts your Hijri date by a day either way, so reminders line up with your local moon sighting. Set it once at signup.
How often will you email me?
Only the evening before a recommended fasting day — and coinciding days (say a Monday that’s also a White Day) come as one combined email, never two. On top of that, a short Jumuah email every Thursday evening, Insha Allah.
What’s the Jumuah email?
A gentle Friday-prep note every Thursday evening: a reminder to read Surah al-Kahf, send extra salawat, and watch for the hour of acceptance. It’s not a fast (singling out Friday to fast isn’t the sunnah), so it even comes during Ramadan — and never nudges you to fast on a Friday.
Can I add Islamic dates to my calendar?
Yes — subscribe to our free .ics feed and the White Days, Ashura, Ramadan, the two Eids, Arafah and more appear in Google Calendar, Apple Calendar or Outlook, refreshing themselves weekly. Grab it in the “Islamic dates & calendar” section above. Free forever, Insha Allah.
Is it really free?
Free forever, Insha Allah. It’s a small gift from IntegrAuth. No ads, no selling your email, ever.
How do I stop?
One click. Every email has an unsubscribe link, and it works instantly.
What about Ramadan and the Eids?
We stay silent all of Ramadan (you’re already fasting), and we never remind you to fast on the two Eids or the days of Tashreeq — those are days to celebrate, not fast.
