A day can mean two different clocks.

Calendar-day mode counts the activation day as day one and stops at midnight after the entered number of calendar days in the selected timezone. Exact-duration mode adds days × 24 hours to the entered trigger time. Unknown mode does not invent an expiry.

This tool supports only Asia/Bangkok (UTC+07:00, no daylight-saving transition) and UTC. If the provider uses another zone, a different cutoff or a distinct calendar-day definition, neither mode establishes that rule.

Illustrative example / Not a provider rule

A late start may be a short first day.

Starting at 23:00 Bangkok time on 1 January with one calendar day gives an expiry at 00:00 on 2 January. One exact-duration day ends at 23:00 on 2 January. The entered rule, not the QR-code scan, determines the planned answer.

Read the calendar as a plan.

The terms-check reminder is a timed UTC event. Calendar-day expiry is an all-day entry on the first day without validity, with an exclusive next-day end; its title names the chosen timezone. Exact-duration expiry is a timed UTC entry. Calendar apps display timed events in their own zone. No event starts or renews a service.

Keep installation instructions available offline, maintain a connection to fetch the profile, and confirm whether an unused profile can be reinstalled. The calendar file stays local and contains your entered label.
