Agreeing contact windows across time zones
Your team works across countries, and someone is always waking up or winding down.
To agree contact windows across time zones, find the hours when everyone is working, write down when each person replies, and share the awkward hours fairly. Put it in writing and try it for a few weeks. Then silence stops being a guessing game.
You do not have to be reachable all day just because someone, somewhere, is at work.
How do I find an overlap?
List each person’s normal working hours in their own time and convert them to one reference time. Mark where they overlap. That overlap is your best place for live calls.
Malaysia has no daylight saving, but colleagues in some other countries move their clocks twice a year. Check the overlap again when that happens, as in checking a recurring meeting when another country changes its clocks.
What should a contact window say?
Keep it short and visible. A good one covers who, when and for what.
- the hours you reply in your own time
- how to reach you for something truly urgent
- what can wait until your next window
- which hours are for live calls
Put it in your chat status or email signature so people see it before they message.
Try this: draft a team agreement
Use this with your colleagues in one sitting.
- Each person writes their usual working hours and time zone.
- Together, mark the overlap and agree it for live calls.
- Outside the overlap, agree that written updates are fine and replies come in the next window.
- Write one rule for urgent items, such as a phone call, and what counts as urgent.
- Agree to review in a month and change what is not working.
A draft might read: “We reply within our own working hours. Live calls happen in the overlap. Urgent items get a phone call, and everything else can wait until the next day.”
How do we share the awkward hours fairly?
If one person always takes the early or late call, resentment grows. Rotate the awkward slot, or give the person who takes it a later start or an earlier finish the next day.
If you cannot find any fair slot at all, our guide on what to do when there is no fair meeting time for everyone goes further.
Adapting it to your real day
If you work from home, a late call can quietly eat your family dinner. Agree the end time with the team, and protect it as you would a meeting. If a manager sets the pattern, bring your draft to them first.
If constant odd-hour messages are costing you sleep or leaving you anxious, please see our support page.
Where to go next
For messages that arrive after you have finished, read discussing after-hours WhatsApp messages with your team. To make the gaps work, see writing an asynchronous handover that does not require an immediate reply.
Everything on this theme is on our work boundaries guides.
If you would like to close a late day more gently, Sadhguru’s free seven-minute guided meditation in the Miracle of Mind app is an optional place to start.
Common questions
What is a contact window?
It is a set stretch of time when you are expected to reply, written down and shared with your team. Outside it, messages can wait. Windows make expectations visible, so nobody has to guess whether silence means they are being ignored.
What if there is almost no overlap in working hours?
Then plan more work as handover notes and fewer live calls. Agree who takes the early or late call and swap it over time. Our guide on asynchronous handovers covers how to write them.
Do I need my manager to agree?
It helps a great deal, because a window only works if the people sending requests respect it. Propose it to your manager and team together, with the draft in writing, and ask for a trial period.
