How many pairs work for your week?

The arithmetic, made visible.

The planner rounds laundry days divided by wears per pair up to the next whole pair, then adds your backup pairs. It subtracts the usable pairs you already own to show a possible gap. This assumes you wear one pair for each day in the interval and that clean laundry is ready at the end.

For example, seven days between loads and two wears per pair needs four pairs in rotation. One backup makes five. If you already own three usable pairs, the planning gap is two. Those numbers are an illustration, not a recommendation about how often you should wash clothing.

If a pair is unavailable during a longer drying cycle, add that delay to your laundry interval. Exclude pairs that no longer fit or that you do not actually wear. Buying nothing is a valid result when your existing drawer covers the routine.
