Keeper.sh now uses the latest time-zone rules when it copies an event. After Alberta stopped changing its clocks on 1 November 2026, copies of events in affected zones could land an hour early in the other calendar. They now land at the time the original shows.
The update covers Windows' new names for the Alberta, British Columbia and Manitoba zones, which Outlook and Microsoft 365 calendars use, so events from those calendars resolve to the right zone too.
A second fix covers calendars that describe a zone's later clock changes as a list of dates rather than a repeating rule, as some calendars do for Asia/Manila. Keeper.sh now reads those zones by the official rules, so their copies land at the right time as well.
An event has not arrived in the other calendar covers what to check when a copy looks wrong.
