These guides are for anyone who sends calendar invites across regions: product and engineering leads, executive assistants, and travelers who still book calls by hand. Each post focuses on one class of mistake—ambiguous time labels, daylight saving drift, asymmetric geographies, or “fair” rotation—and ties back to TimeZoneMeet when a quick city check or the Schedule tool can prevent it.
Posts are written to be readable in one sitting. When regional rules or our product behavior change in a way that affects advice, we revise the page and adjust the visible date where it makes sense.
Three pillars that cover most real-world scheduling pain.
Start with overlap thinking, write wall-clock times with a clear zone or UTC reference, and re-check around daylight saving transitions. This is the best first read if your team spans more than two regions.
Define a local-hours band (for example roughly 5am–8pm) and reject any slot that violates it for any required attendee—including the end time of the meeting, not only the start.
Half-hour offsets and “IST = UTC+5:30” shortcuts trip people up. This post walks through reliable patterns and quick verification steps before you send the invite.
Bookmark these alongside the lookup tool.
A reference page covering 30+ popular city pairs across US ↔ Europe, US ↔ India, US ↔ APAC, three-region combinations, and the offset quirks (half-hour zones, opposite-hemisphere DST, the Spain-Portugal split). Updated whenever zone rules change.
