Create a period with a start, an end and a label, see the twelve months ahead at a glance, delete one. The label is required and trimmed: it goes straight onto the shop window. Overlapping periods are refused, and the message names the one they collide with. Two rows covering the same day would both be "in effect" with no way to say which, and silently merging them would lose whichever label the owner meant. Periods that merely touch — one ending the 10th, the next starting the 11th — are fine. The year view exists because a list of date ranges is precise and hard to picture, while "have I left a gap in August?" is the question people actually ask. It renders on the server; it only changes when the data does. A vacation period stays a source of truth and is never expanded into exception rows, so a one-off exception placed inside one still wins and nothing is overwritten. The page says so rather than leaving it to be discovered. The first version of the calendar built the months but never applied the periods to them, so no closure would ever have shown.
