Lesson time zone overlap finder
Teaching students in three countries means holding three clocks in your head. Pick your city and theirs — see exactly which lesson hours work for everyone, before you offer a slot at someone's 3am.

Why does time zone scheduling go wrong?
Three failure modes account for nearly every missed international lesson. The first is the silent assumption: “see you at 6” means your 6 to you and their 6 to them, and nobody notices until one of you is alone on the call. The second is daylight saving drift: Europe and North America change their clocks weeks apart, so for two stretches every year a perfectly stable lesson time silently moves an hour for one side — and countries near the equator never move at all. The third is 12-hour ambiguity: a student who reads “7:00” as evening when you meant morning.
All three have the same cure: make the time explicit in the student's own clock, in writing, with a calendar invite to carry the time zone for you. We've collected the full set of habits in scheduling international tutoring across time zones.
How do you build a schedule around the overlap?
Treat the green hours in the grid as your international prime time and protect them. If your Vietnam-based students can only meet in your morning and your Brazil-based students only in your evening, the overlap tells you which hours to reserve for which region — and which local-market hours stay free for students in your own time zone. Tutors who grow internationally usually discover their calendar has two or three of these regional bands, and the schedule becomes much calmer once lessons are clustered into them instead of scattered.
The overlap also feeds your pricing: scarce, in-demand hours (your early evening, which is mid-evening across Europe and morning in the Americas) are worth protecting for your best-paying regulars — if you're working out what those hours should cost, the tutoring rate calculator is the companion tool to this one.
Frequently asked questions
How do I avoid time zone mix-ups with students?⌄
Two habits prevent nearly all of them: always state lesson times in the STUDENT'S time zone ("Tuesday at 18:00 your time"), and always send a calendar invite — calendar events carry the time zone with them, so each side's calendar shows the right local hour automatically. Mix-ups almost always come from a bare "see you at 6" where each person silently assumed their own clock.
What happens to lesson times when the clocks change?⌄
If your country observes daylight saving and the student's doesn't (or changes on a different date — the US and Europe shift weeks apart), a lesson that's fixed in your time moves an hour in theirs. The weeks around late March and late October are when reliable students suddenly arrive an hour wrong. Send a short heads-up message both weeks, and re-check your overlaps in this tool after each change.
What's a reasonable hour to ask a student to take a lesson?⌄
The tool defaults to 07:00–21:00 in the student's local time, which covers most motivated adults — early-morning lessons before work are surprisingly popular with business English students. Push beyond that range only when the student suggests it themselves, and never for younger learners, whose attention follows the school day.
Which time zone should a recurring lesson follow?⌄
Pick one anchor — usually the tutor's time zone — and say so explicitly when you set the recurring slot. The lesson then stays fixed for you and shifts for the student only when one of you changes clocks, which you handle with the twice-a-year heads-up message. The alternative (anchoring to the student) works too; what breaks things is never deciding.
How does Tuton handle student time zones?⌄
Automatically. Your Tuton booking page shows your availability in each student's own local time — they book a slot that's correct for both of you without anyone converting anything — and lesson reminders go out in their time. Time zone mix-ups are one of those problems best solved by software rather than vigilance.
Or let the booking page do the converting.
On Tuton, students see your availability in their own time zone and book a slot that's right for both of you — no conversions, no 3am surprises, automatic reminders in their local time. See how scheduling & booking works.
