- How far in advance should I prepare for a DST transition?
- Start at least two weeks before the transition. This gives you time to audit recurring meetings, notify external partners, verify that your calendar tools have updated time zone data, and adjust any meetings that will land in a problematic slot after the shift.
- Do calendar apps handle DST automatically?
- Most modern calendar applications adjust recurring meetings automatically if the event was created with a time zone attached. However, events created with a fixed UTC offset rather than an IANA zone will not adjust. It is worth verifying your critical meetings manually.
- What about the gap weeks when some countries have changed and others have not?
- The US transitions in early March and early November, while Europe transitions in late March and late October. During the two-to-three-week gap, offsets between US and European cities shift by one hour. Review all cross-Atlantic meetings during these periods.
