Studied something today? Enter the date you studied and your exam date, and we'll build a spaced repetition review schedule — the exact days to review so you remember it on exam day instead of forgetting it.

How the spaced repetition schedule works

You don't forget because you're not smart — you forget because you review at the wrong time. Spaced repetition means reviewing material at increasing intervals (1 day, 3 days, a week, two weeks…), each time just before you'd naturally forget it. This calculator takes the day you studied and your exam date, and lays out the exact review dates so the material is still fresh when it counts.

• Increasing intervals — each review is spaced further apart than the last, which strengthens long-term memory.
• Anchored to your exam — reviews that fall after your exam are dropped, and a final review is added right before the test.
• One topic at a time — run it per subject or chapter; then drop the review days into your study timetable.

FAQ

What are the best spaced repetition intervals?

A common, well-tested pattern is 1, 3, 7, 14, and 30 days after first studying. If your exam is close, use the intensive option; if it's far off, the light option is enough to hold the material.

Is this the same as Anki?

Anki decides review timing card by card while you drill. This tool is a planner: it gives you the calendar of review days for a whole topic, so you can schedule them — with or without flashcards.

When should I review after studying?

The first review is most important within 24 hours. After that, space reviews out. This calculator shows the exact dates for you.
