Scheduler — the appointment book — Repeating bookings, and changing just one

A repeating booking is stored once, as a rule, and drawn for whatever period you are looking at — so “every Tuesday, forever” is literally true and costs nothing to keep. Generated bookings are drawn with a faint hatch because they are not records yet. Move or cancel one and the scheduler asks how far the change should reach: • Just this one — the rule skips that date, and the one booking becomes a record of its own you can edit freely. This is how you handle “same as usual, but an hour later this week”. • This and all later ones — the old rule stops here and a new one starts, so everything before today is left exactly as it was. This is the one you want for “from now on we do Wednesdays”. • The whole repeat — changes every booking in the series, including ones already past. You are only asked when it could matter. A one-off booking just moves.
