Scheduling client meetings across time zones on Mac in 2026: find the overlap
To schedule client meetings across time zones on a Mac, find the hours when both calendars are free, then offer two or three of those hours. Outlook and Apple Calendar can show the overlap, but only if the calendars are set up to share it. This guide covers how to find the overlap, where the tools fail, and what you can do without buying anything.

The short answer
- Read the overlap from both calendars before you write the message.
- Offer two or three slots, and write the time zone beside each one.
- Mark false blocks as Free, so real openings show up in the view.
- Propose a new time inside the invite instead of starting a new chain.
What finding overlapping slots across time zones costs you
Wage time on the email chain
The BLS puts the median management analyst at $48.97 an hour in May 2025. Consultant rates are not the same, so use that figure as a rough anchor. At that rate, 30 minutes of coordination costs about $24 in wages alone. That leaves out benefits, overhead and the meeting itself. Multiply that by every client you schedule each week.
Meetings that accomplish nothing
Doodle's 2020 release says 59% of full-time Fortune 500 executives attended meetings that were poorly managed and accomplished nothing. The release does not state its sample size, and Doodle sells scheduling software. Treat the number as a signal, not a measurement. The same release says over a quarter of surveyed employees spent 20 or more hours in meetings in one week.
Reschedules and the wrong zone
A message that forgets the client's zone can put the meeting in the middle of their night. You then reschedule, which adds another round of messages. Each round costs you time on both sides, and the client may read the mistake as a sign of how the rest of the work will go.
Your focus hours
Microsoft reports that 50% of meetings take place between 9 to 11 am and 1 to 3 pm, which the report calls prime focus hours. Meetings that start after 8 pm rose 16% year over year. When a client's window sits far from yours, the search pushes into your focus hours or past 8 pm.
Why it happens
Calendars do not share availability by default
Your calendar and your client's calendar rarely show each other's free time by default. Apple's Check Availability option appears only for events on a calendar service that tracks availability, such as CalDAV. Google's Find a time shows a guest's status only when that guest has shared their calendar with you. If neither applies, you are guessing from memory.
Time zones multiply the search
Microsoft's methodology section says about 30% of meetings span several time zones, and that share has risen since 2021. Each extra zone shrinks the set of hours that work for everyone. Two zones can still leave a workable strip. Three or more can leave a narrow strip, or none at all.
Scheduling runs one message at a time
Microsoft's follow-up reports 57% of meetings are ad hoc calls without a calendar invite. Its methodology section gives 60% for unscheduled meetings, so the true share sits near that range. A question like Are you free Tuesday? starts a chain. Each answer invites another question, and the chain grows.
Your own calendar hides real openings
A Busy event blocks a slot even when you could move it. Calendly's help page lists a Busy event, a disconnected calendar and a minimum notice setting as reasons a time looks blocked when it should be open. Your calendar app can hide openings in the same way, so check your side first.
Bookings land at the last minute
Microsoft reports that 1 in 10 scheduled meetings are booked at the last minute. A late request leaves little room to check two zones, two sets of hours and two calendars. When the overlap is narrow, a late request may have no overlap left at all.
How to fix it
These work with or without any app.
Check overlap in Outlook with Scheduling Assistant
If you use a work or school account, open a new meeting and add the client. Scheduling Assistant shows each attendee's schedule and helps you find a time everyone is free, according to Microsoft's Outlook for Mac help page. Menu names change between Outlook versions. If you cannot find it, search the Outlook help for Scheduling Assistant.
Use Check Availability and Propose a New Time in Apple Calendar
Open the event info window, then look for Check Availability. The option appears only for events on a calendar service that tracks availability, such as CalDAV. Propose a New Time needs the same kind of service, and it lets the guest comment to you. On other services, Apple says the organizer may only get an email.
Use Find a time in Google Calendar
Click Create, add the guest, then select Find a time. Google shows a guest's availability only if they have shared their calendar with you. Ask the client to share their calendar before you rely on that view, or send them a short list of slots instead.
Clear false blocks in your own calendar
Open each event that blocks a slot you could move. Mark it as Free if you are not actually busy. Check that each calendar connection is still live. Calendly's help page recommends reconnecting a calendar that shows as not connected. Do this once a month, and the view gets more accurate.
Offer two or three slots with both zones written out
Pick two or three times from the overlap, and write each one twice. For example, 10:00 AM Chicago (4:00 PM London). Let the client choose from that short list. One message with clear options ends the chain faster than an open question does.
Use a booking link only for repeat clients
A booking page can show open times and enforce a minimum notice. Calendly's help describes free/busy rules that let overlapping meetings through. Its pricing page lists a Free plan with one calendar connection, while Standard and Teams both allow six. Check the pricing page before you pick a plan.
Keep one short list of windows per client
Write each regular client's working hours in their zone, next to your own, in one note. Read the overlap from that note before you open any calendar. This takes a few minutes, and it removes the first round of questions every time you propose a meeting.
Most scheduling advice starts with a tool. This page starts with the overlap, because a tool only helps once you know which hours to offer. The overlap is the set of hours when both people are at work and free. Everything else is a detail that follows from it.

How to find the overlap on a Mac, step by step
- Write your own working hours in your time zone. Use one range, such as 9 am to 5 pm.
- Write the client's working hours in their zone. If you are not sure of them, ask once.
- Pick one zone to compare in, and write the other zone beside it.
- Open the shared view. In Outlook, use Scheduling Assistant. In Apple Calendar, use Check Availability on the event.
- Read the strip where both ranges and both calendars are free. Note the first two or three slots.
Here is a worked example. You work in Chicago, and your client works in London. Your window is 9 am to 5 pm local, and so is theirs. Put both windows on one timeline, and the overlap sits late in your day. In this case the strip is about two hours long, which is enough for a one-hour call with room to spare.
How to propose a new meeting time without the email chain
Propose two of those slots in one message. Name the zone beside each one, such as 3 pm London (9 am Chicago). Keep the third slot as a backup. If the client picks none of them, ask which hours suit them, then send a fresh overlap built from their answer.
Which Mac tools show the overlap, and what they need
| Tool | Where the overlap shows | What it needs |
|---|---|---|
| Outlook (work or school account) | Scheduling Assistant in the meeting form | A work or school account, per Microsoft's Outlook for Mac help page |
| Apple Calendar | Check Availability and Next Available Time on the event | An event on a calendar service that tracks availability, such as CalDAV |
| Google Calendar | Find a time, after you add the guest | The guest must share their calendar with you |
| Calendly (booking page) | Free/busy rules and minimum notice on a booking link | Free plan allows one calendar connection. Standard is $10 per seat per month, billed annually |
The tools help only when the calendars can see each other. If the client's calendar is closed to you, the view shows nothing useful, and you must ask once. Menu names also shift between Outlook versions. If a name on this page does not match your screen, search the help page for the feature name instead of the menu path.

Mistakes that create wrong-time meetings
- Sending only your own zone in the invite and leaving the client to convert it.
- Offering a slot right after a Busy event you could easily move.
- Assuming a recurring series stays right all year. Daylight saving changes do not happen on the same day in every country.
- Setting the minimum notice so high that the next day never shows as open. Calendly's help page calls this TOOSOON.
- Sending one proposal and then waiting a week for a reply.

median hourly wage for management analysts in May 2025, a rough cost anchor
BLS Occupational Outlook Handbook: Management AnalystsThree or more zones and recurring series
Three or more zones change the search. Start from the zone of the person with the least flexible hours. Build the overlap around them, then test the other zones against that short list. If nothing fits, ask the group which hours each person can move, and rebuild from those answers.
Recurring series need a second check. Daylight saving changes do not all land on the same day in every country. A weekly slot can feel wrong for a short stretch each year, when one country has changed its clocks and the other has not. Check the series once each season, and ask the client whether the time still works for them.
What to do next
Start with one client you meet often. Write their hours and yours in one note. Use Scheduling Assistant or Check Availability for the next proposal, and note which view showed the overlap more clearly. That one comparison tells you more than any checklist.

Handles the small stuff
A plan you can start this week
- Day 1
Write your windows once
Write your working hours in your zone, and the zone of each regular client. Keep them in one note. Include the days you never take meetings. This takes a short sitting, and it saves the first round of questions.
- Day 2
Clear false blocks
Open the calendar events that block your open time. Mark events you do not need as Free. Check that each calendar connection is still live, and reconnect any that show as disconnected.
- Day 3
Test one shared view
Pick your most frequent client. In Outlook, open a new meeting and check Scheduling Assistant. In Apple Calendar, check whether Check Availability appears on an event. Note which view works for that client, and why.
- Day 4
Send one proposal
For the next meeting request, pick two or three slots from the overlap. Write each slot with both time zones. Send them as one message, and ask the client to choose.
- Day 5
Review the chain
Look at the week's threads. Count how many messages each meeting took. Mark the zones that caused the most rounds, and move those windows into your note before next week.
Questions people ask
Can I see a client's free times without asking them?
Usually not. Google's Find a time shows a guest's availability only if they have shared their calendar with you. Apple's Check Availability depends on the calendar service the event sits on. Ask the client to share availability, or send two or three slots and let them pick.
Why does Check Availability not show in Apple Calendar?
Apple's guide says the option appears only for events on a calendar service that tracks availability, such as CalDAV. Check the account the event sits on. If that account does not track availability, the option stays hidden, and a written proposal is the next step.
How many time zones can one meeting handle?
There is no fixed limit. Each extra zone narrows the overlap. Once a meeting spans three or more zones, ask the group which hours are fixed, then build the overlap from those hours.
Does Lazur see my client's calendar?
Lazur listens and looks at your screen only while you hold the shortcut. Audio and the screenshot go to AI providers to answer, and they are not stored. Content is never used to train AI models. Follow your firm's rules on client data before you use it with client details.
Is Calendly free?
Calendly's Free plan includes one event type and one calendar connection. Standard is $10 per seat per month with annual billing, and Teams is $16 per seat per month with annual billing. Check the pricing page for monthly prices, because this guide did not confirm them.
Does Lazur work on Windows?
Not yet. Windows is planned, but it is not available. Lazur runs on macOS, on both Apple silicon and Intel Macs. You can start with a three-day Pro trial that needs no credit card.
