It uses the formula Entry = Ramadan start + 19 days, at sunset; exit = Ramadan start + month length (Eid) to turn your inputs into a reliable result.

Frequently asked questions

When do I enter I’tikaf?
Before sunset on the 20th day of fasting, so you are inside the masjid as the 21st night — the first of the last ten — begins. The calculator pins the exact civil date from your Ramadan start.
When does I’tikaf end?
The I'tikaf Days Calculator is free, private, and accurate: it runs entirely in your browser (no uploads, no accounts), applies the standard calculation, and explains each step so you can verify the result. The I'tikaf Days calculator shows when the last ten nights of Ramadan begin and end, so you can plan your i'tikaf (spiritual retreat) in the mosque. There is no limit on usage, and it works on any device.
What invalidates I’tikaf?
I'tikaf is invalidated by leaving the mosque without a valid excuse for worldly needs, sexual relations, breaking the fast during Ramadan i'tikaf without excuse, and apostasy or major ritual impurity. Essential needs — using the toilet, wudu, buying food nearby — are allowed. The calculator helps you plan the days; the validity rules follow the classical fiqh conditions.
Can women perform I’tikaf?
Yes — women may perform i'tikaf in the mosque when proper arrangements and segregation exist, and many scholars permit it in a designated prayer space at home if the mosque is not accessible. The conditions are the same as for men: intention, staying in the place of i'tikaf, and avoiding the invalidating acts. The calculator works for any dates you choose.
Is a shorter I’tikaf valid?
Yes — the minimum accepted i'tikaf is a stay with the intention of worship; it does not require the full ten days of the last third of Ramadan. A night, an hour, or even a brief stay counts as sunnah i'tikaf when done with the right intention. The calculator lets you enter any start and end date to plan your stay.
