Email Response-Time calculator

Paste your threads, one per line, and every reply time converts to working minutes: lunch, weekends and holidays drop out, and each thread gets a breach flag against your target.

This is first-response arithmetic on what you paste, not a mailbox connection: nothing is fetched, and the numbers are only as good as the lines you type. Times are treated as plain wall clock, so daylight-saving shifts inside a counted interval are not modelled, seconds are dropped, and an overnight support window is out of scope. Median and p90 interpolate linearly between order statistics. A zero-minute reply counts as within target.
