What are the limits of Availability Calendar Maker?
Select 1–180 dates, 1–4 non-overlapping same-day windows, slot length 5–240 minutes and an optional gap. Creates complete slots only, up to 5,000. These are offered times, not confirmed bookings; calendar exports mark them as free. Dates are interpreted in the selected IANA timezone; DST ambiguities are rejected. Calendar artwork marks available days; CSV and ICS retain exact time slots. No booking link, live availability sharing or account integration. All files, events, names and notes stay in browser memory. No calendar-account connection, upload, external model, background reminders or automatic storage. Refreshing clears the workspace; save an export to keep your work. Exported calendar files require an explicit import into a calendar app; they do not create reservations or synchronize changes.
