How to Schedule Meetings Across Multiple Time Zones

Coordinating a meeting across two cities is manageable. Coordinating across three, four, or five quickly becomes a logistics puzzle. Remote teams, global clients, and international travel all push schedulers to find narrow windows where everyone can be awake, alert, and online at the same time. This guide walks through the practical realities of multi-zone scheduling, the common pitfalls, and the strategies that experienced teams use to keep meetings fair and productive.

Why Multi-Time-Zone Scheduling Is Difficult

Once you add a third or fourth city to a meeting, the math compounds. Every additional location reduces the natural overlap of business hours. A two-city call between New York and London has roughly four hours of comfortable overlap. Add Dubai and the overlap shrinks to a single hour. Add Tokyo and you may have no shared window at all.

The challenge is not just finding the right hour. It is finding an hour that is reasonable for everyone, that respects local working norms, and that does not consistently burden the same people with very early or very late calls.

Understanding Overlap Windows

The first step in any multi-zone schedule is to map the overlap. Define the working hours of each location, typically 9:00 AM to 6:00 PM local time, then look for the time slots that fall within working hours for everyone. The result is the overlap window. For some combinations, the window is generous. For others, it does not exist and someone will have to compromise.

A practical heuristic: if the largest time gap between any two participants exceeds nine hours, you will not find a comfortable shared window. You will need to either rotate meeting times, split the team into regional sub-meetings, or ask one location to flex outside normal hours.

Practical Examples

New York, London, and Dubai

This trio is one of the most common in international finance and consulting. New York is UTC-5 (or UTC-4 in summer), London is UTC+0 (or UTC+1), and Dubai is a fixed UTC+4. The overlap window is narrow but workable. A meeting at 8:00 AM New York time corresponds to 1:00 PM London and 5:00 PM Dubai during standard time. That puts everyone within a normal working day, though Dubai sits at the end of theirs and New York at the start.

Los Angeles and Tokyo

Los Angeles and Tokyo sit roughly sixteen to seventeen hours apart depending on DST. There is no overlap during normal business hours. Teams that need to collaborate often run early-morning calls in Los Angeles, around 7:00 AM, which corresponds to 11:00 PM the same day in Tokyo. Or they push the call to 5:00 PM Los Angeles time, which is 9:00 AM the next day in Tokyo. Either choice asks one side to stretch their day.

Chicago and Sydney

Chicago is UTC-6 in standard time and Sydney is UTC+11 in their summer (which corresponds to U.S. winter), creating a seventeen-hour gap. This is one of the trickiest pairings because both cities also observe DST, but in opposite seasons. The result is a relationship where the time difference shifts between sixteen and eighteen hours throughout the year. A 4:00 PM Chicago call typically lands around 8:00 AM the next day in Sydney, which works for both sides if scheduled carefully.

Remote Work Challenges

Distributed teams have made multi-zone scheduling a daily concern rather than an occasional event. The most successful remote teams treat synchronous meetings as a scarce resource and lean heavily on asynchronous communication. Documents, recorded videos, and threaded discussions reduce the need for live calls. When a meeting is necessary, teams often agree on a small number of fixed time slots that recur weekly, so calendars can be built around them rather than negotiated each time.

DST Complications

Daylight saving time can quietly break a recurring meeting. When New York shifts forward in March but London has not yet shifted, the time gap temporarily narrows from five hours to four. A standing call that worked all winter suddenly arrives an hour earlier than expected. The reverse happens in fall. Teams that span DST and non-DST regions, such as anything involving Tokyo, Dubai, or Phoenix, see the gap change without warning.

The safest approach is to rely on calendar tools that store meetings in the organizer's local time and convert automatically for each attendee. Verbal or text confirmations should always include the time zone, and recurring meetings near a transition date should be double-checked.

Fairness Across Regions

When no time slot works for everyone, someone has to take the inconvenience. The fairest approach is to rotate. If your team spans New York, London, and Tokyo, schedule the same meeting at three different times across three weeks so that each location is the inconvenienced one in turn. This builds trust and prevents resentment, especially when the inconvenienced location is consistently the smallest or most junior office.

Another option is to split the meeting. A single global call can become two regional calls with a written summary shared between them. This loses some of the live interaction, but it keeps everyone in normal working hours.

Recommended Meeting Windows

For common multi-zone teams, a few windows show up repeatedly as the least painful options.

• U.S. East Coast and Europe: 8:00 to 11:00 AM Eastern Time.
• Europe and Asia: 7:00 to 9:00 AM in Europe, which is afternoon in most of Asia.
• U.S. West Coast and Asia: 4:00 to 6:00 PM Pacific Time, which is morning the next day in Asia.
• U.S., Europe, and Middle East: 8:00 AM Eastern, 1:00 PM London, 4:00 PM Dubai.
• U.S. and Sydney: 3:00 to 5:00 PM Pacific Time, which is morning the next day in Sydney.

Tools That Simplify Scheduling

Manual calculations work for two cities. For three or more, dedicated tools are faster and far less error prone. The Meeting Time Planner on NowTimeHub shows the local hour in every selected city side by side and highlights overlap windows automatically. The Time Zone Converter handles quick one-off conversions, and the World Clock displays multiple cities at once for at-a-glance planning.

Calendar applications such as Google Calendar, Outlook, and Apple Calendar can display a secondary time zone next to your primary one. Turning this on for the cities you work with regularly removes most of the cognitive load. For frequent travelers and global teams, the small setup investment pays off every week.

Frequently Asked Questions

What is the best way to schedule across time zones?

Use a meeting planner tool to map overlap windows across all participating cities, then pick a time that falls within working hours for as many people as possible. For groups that span more than nine hours of difference, plan to rotate inconvenient slots fairly.

How do remote teams coordinate meetings?

Successful remote teams favor asynchronous communication for most updates and reserve live meetings for true collaboration. They often establish a small number of fixed weekly time slots and use shared calendars with multiple time zone displays.

What tools help compare multiple time zones?

Meeting planners, world clocks, and time zone converters are the core tools. NowTimeHub offers all three for free and updates them in real time, including for daylight saving transitions.

How does DST affect global meetings?

DST temporarily changes the time difference between cities, especially when one location observes it and another does not. Staggered transition dates can also create brief windows where the gap is off by an hour for a week or two. Recurring meetings near the spring and fall transitions should always be double-checked.

Final Thoughts

Multi-zone scheduling is a craft, not a one-time calculation. The teams that do it well combine the right tools, clear conventions, and a sense of fairness about who absorbs the inconvenience. With practice, what feels like a puzzle at first becomes a quick weekly routine, and your global team gets to focus on the work itself rather than the logistics of when to start.
