Spaced repetition scheduler
Memory decays on a curve, fast at first, then slower. Reviewing right before you would forget resets the curve and flattens it, so each review buys more time than the last. Pick a start date and how many reviews, and get the dates to actually retain what you learned.
Intervals expand (1, 3, 7, 16, 35, 75, 150, 300 days). Adjust to your own recall; if you blank on a review, shorten the next gap.
Why spacing beats cramming
Hermann Ebbinghaus mapped the forgetting curve over a century ago: without review, most of what you learn is gone within days. Each well-timed review re-strengthens the memory and stretches the interval before the next one, which is why ten minutes spread across six sessions beats an hour in one. It is the single highest-leverage study technique known, and it pairs directly with learning anything faster.
