Meeting Time Across Time Zones Calculator

Work out meeting time across time zones instantly with clear inputs, formula shown and shareable results.

About Meeting Time Across Time Zones Calculator

Converting between zones runs through UTC: subtract the host offset to get UTC, then add the participant's offset. A 14:00 meeting at UTC+1 is 13:00 UTC, which is 08:00 for a participant at UTC-5. Where the result falls outside 0-24 the day shifts, which is what catches out Asia-Pacific scheduling.

Formulas

Convert via UTC

UTC = local - offset; participant local = UTC + their offset

Day shift

adjust by 24 hours and record the day change

Worked example

With the default values below, Meeting Time Across Time Zones Calculator returns Participant Local Time of 8.00. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Why go through UTC?

Because it removes the need for a matrix of zone-to-zone differences. Every zone is defined by its UTC offset.

Do half-hour offsets exist?

Yes - India is UTC+5:30, Nepal UTC+5:45 and parts of Australia UTC+9:30, which is why offsets are entered as decimals.
