How to find a meeting time across time zones

  1. Set your home time zone

    The tool defaults to the time zone your browser reports, or pick one from the list.

  2. Add up to four other time zones

    Type a city or region and press Enter to add each person or office you are scheduling around.

  3. Set the working-hours window

    Choose the start and end hour that counts as working hours, applied to every zone on its own local clock.

  4. Read the grid and the summary

    Each row shows the local hour and shading for every zone, and a summary line names the best overlapping hours or says there is none.

Why use this tool

Up to five time zones at once

Compare a home time zone against up to four others on a single grid, each drawn from a curated list of common cities and regions.

A 24-hour grid, shaded three ways

Every zone gets a row of 24 hours, shaded as inside working hours, just outside them, or night, so a scan of the grid shows the shape of everyone's day at a glance.

One shared working-hours window

Set a single start and end hour and it is checked against each time zone's own local clock, not translated through any one zone.

A plain-language overlap summary

A summary line names the hours, in your home time, when every selected zone is inside its own working hours, or says plainly that there is no shared window.

Handles daylight saving correctly

Each hour on the grid is resolved against the current date, so the comparison reflects the daylight saving rules in effect right now.

One-click copy of the schedule

Copy schedule turns the whole grid and its summary into plain text, ready to paste into an email or a chat.

About this tool

This tool lines up a home time zone against up to four others on a single 24-hour grid, so scheduling a call across offices or time zones does not require converting each hour by hand. The header row runs through your home time zone's 24 hours, and each zone below it shows what its own local hour is at that same instant, shaded as inside working hours, just outside them, or night.

The working-hours window, 9 to 17 by default, is applied to every zone's own local clock rather than translated through the home zone, so a cell only counts as "inside working hours" if it genuinely falls in that person's normal day. A summary line beneath the grid names the home-time hours where every selected zone is inside its working-hours window at once, or says plainly that no shared window exists, which happens with time zones on opposite sides of the globe.

The whole comparison runs in your browser using the current date, so the daylight saving rules in effect right now are reflected correctly, and nothing you select is uploaded. To convert a specific date and time between zones instead of comparing working hours, use the timezone converter; to see the current time in several places side by side, use the world clock; and to work out a duration once a time is agreed, use the duration calculator.

Frequently asked questions

How many time zones can I compare?
One home time zone plus up to four other time zones, for five rows on the grid in total, chosen from a curated list of common cities and regions.
What do the three shades on the grid mean?
The darkest shade marks hours inside the working-hours window for that time zone, a middle shade marks the hour or two just outside it, and the lightest marks night hours well outside working hours.
Is the working-hours window the same clock time for every zone?
No. The start and end hour you set is checked against each time zone's own local clock, so 9 to 17 means 9am to 5pm in that zone's own day, not a single moment shared by all of them.
What happens if there is no overlapping working time?
The summary line says plainly that no hour falls inside working hours for every selected zone, which is common for time zones on opposite sides of the world.
Does the grid account for daylight saving time?
Yes. Each hour on the grid is resolved against today's date in every zone, so the comparison reflects whichever daylight saving rules are currently in effect.
