Common mistakes

Assuming it's a global rule. Many countries don't observe daylight saving time at all, and those that do often change on different dates than the US.
Mixing up the direction. "Spring forward" in March loses an hour; "fall back" in November gains one back.
Forgetting it shifts your UTC offset. A clock change can move your time zone's offset even when a meeting's local time doesn't change — check the time zone meeting calculator if you're coordinating across countries near a transition date.
