The gaps grow wider on purpose. Each time a memory survives a longer gap, it holds longer still, so the next review can safely wait. At every review, test yourself first (try to recall it from memory), then check. Rereading feels productive but does far less for retention than pulling the answer out of your own head.
Why these intervals
Learn something once and most of it slips away within days. That is the forgetting curve at work, and the fix is not to study harder in one sitting but to come back to the material a few times, spaced out. Each preset here spreads your reviews across expanding gaps: a day, then a few days, then a week or two, then a month. The first review catches the memory before it fades, and every review after that resets the clock and makes the next drop-off slower, which is why the gaps can safely keep growing.
This is the spacing effect, one of the most reliable findings in memory research. Across 317 experiments, Cepeda and colleagues found that spreading study out beats massing it into one block, and that the best gap grows with how long you want to hold the memory. The same review count, spaced instead of crammed, buys you far more retention for the same effort.
Spacing pairs best with self-testing. Dunlosky and colleagues rated both techniques high utility out of the ten they reviewed, so at each date below, try to recall the material before you check it.
