How to use the flashcard spaced repetition scheduler
- Pick the day you learned the material. It starts as today.
- Enter your review intervals in days, separated by commas. The 1, 3, 7, 14, 30 shown is an example spacing.
- Choose whether each interval counts from the learning day or from the previous review.
- Read the dated schedule, then copy it or add the dates to your own calendar.
Formula
counting from the learning day: review date = learning day + interval
counting from the previous review: review date = previous review + interval
days since the previous review = this interval - the one before it (first mode)
Dates are calendar dates, so month ends and leap days are handled for you.
Learn on January 1
Learning something on January 1, 2026 and counting from the learning day with intervals 1, 3, 7 and 14 gives reviews on January 2, January 4, January 8 and January 15. The gaps between them are 1, 2, 4 and 7 days.
Counting from the previous review with 1, 3 and 7 days, starting on February 27, 2028 (a leap year), gives February 28, March 2 and March 9. The page counts February 29 correctly.
What spaced review is
Spaced review means revisiting material at growing gaps instead of cramming it all at once. Many learners find that short reviews on a spread-out schedule make facts easier to recall than one long session. This page does not predict how well you will remember anything. It simply turns your chosen gaps into dates you can follow.
Start with the example spacing, then adjust. If a topic feels shaky, bring the next review closer. If it feels easy, space it further out. Keeping the dates on a list removes the need to remember when to review.
Pairing it with other study tools
Make the cards with the Flashcard Maker, plan the weeks before a test with the Exam Study Planner, and check the hours you can give each week with the Study Hours per Week Calculator. A Pomodoro Timer keeps each short session focused.
Assumptions and limits
- The intervals are your own plan. They are not tied to a particular memory model.
- All days count, including weekends and holidays.
- When counting from the learning day, each interval must be larger than the one before.
- The page stores nothing. Copy the schedule or download the CSV to keep it.
Frequently asked questions
How do I make a spaced repetition schedule?
Pick the day you learned the material and a list of gaps such as 1, 3, 7, 14 and 30 days. Each gap becomes a review date counted from the learning day or from the previous review.
What are good spaced repetition intervals?
There is no single right set. A growing sequence such as 1, 3, 7, 14, 30 is a common starting example. Shorten the gaps for hard material and lengthen them for easy material.
What is the difference between the two counting modes?
Counting from the learning day sets every review at a fixed distance from the start. Counting from the previous review stacks the gaps, so each review is a set time after the last one.
Can I use this for something other than flashcards?
Yes. Use it for a language, a speech, a musical piece or any material you want to revisit on a schedule.
