How to Plan a Meeting Across Time Zones Worldwide
Short answer
List every participant’s IANA time zone, pick a date (DST matters), and find hours when all are awake — ideally in working hours. A colour-coded meeting planner is faster than doing offsets by hand.
Remote teams search for a “meeting planner worldwide” because chat threads full of “what’s that in my time?” waste hours. Use a shared grid instead of mental UTC math.
Step 1: Collect zones, not just cities
Prefer zones like America/Chicago or Europe/London. City names can be ambiguous; IANA names are not.
Step 2: Fix the date
Daylight saving starts and ends on different dates. Converting “next Tuesday” without a date is how London and New York get an hour wrong every spring.
Step 3: Find the overlap
Look for green (working hours) columns that work for everyone. If none exist, rotate early/late slots fairly. The meeting planner highlights the best column automatically.
Step 4: Put local times in the invite
Write “15:00 London / 10:00 New York / 19:30 Mumbai” so nobody converts again. Double-check with the time zone converter.
Recurring meetings
When DST changes, revisit the slot. For multi-day workshops, the date difference calculator helps span weekends.

More worked numbers
Change one input at a time so you build intuition. Write the formula, substitute values, then confirm with the free meeting planner. If the tool disagrees with your hand math, check units first (months vs years, percent vs decimal, inclusive ranges).
Common mistakes to avoid
- Mixing up percent and decimal forms (15% is 0.15, not 15).
- Using the wrong base when calculating a change or a reverse percentage.
- Ignoring fees, tax or daylight saving when the real-world total depends on them.
- Rounding too early in multi-step arithmetic.
How to practise
Invent three mini-problems from your own life — a bill, a grade, a trip, a loan quote — and solve them on paper before you open the calculator. Teaching the steps to someone else is one of the fastest ways to lock in the method.

Frequently asked questions
What is the best tool for worldwide meeting times?
A side-by-side meeting planner that understands DST, like ours. Double-check units and confirm with the linked tool on this page before you rely on the figure for money or school decisions.
How many time zones can I compare?
Our planner supports multiple cities; keep groups small enough that a real overlap still exists. Double-check units and confirm with the linked tool on this page before you rely on the figure for money or school decisions.
Should I schedule in UTC?
UTC is great for engineers; for mixed teams, list each person’s local time in the invite. Double-check units and confirm with the linked tool on this page before you rely on the figure for money or school decisions.
What if there is no perfect overlap?
Rotate inconvenient slots, shorten the meeting, or split into two regional syncs. Double-check units and confirm with the linked tool on this page before you rely on the figure for money or school decisions.
