How to Schedule Tutoring Lessons Across Time Zones (Without Missing a Class)

To schedule tutoring lessons across time zones without missing a class, fix each lesson in one anchor time zone, the clock of the person who cannot move their day (a child at school, a student with a shift), and show everyone else the converted time with a city name and a UTC offset in the booking page, the confirmation and the reminder. Do that and a 6 pm lesson stays a 6 pm lesson for the person who needs it to be.

The part that catches tutors out is not the offset, which anyone can look up, but the clock changes. The United States and Europe do not move their clocks on the same day, and many countries never move them at all. So a lesson you set once in September can arrive an hour early or late in November for one person and not the other. This guide gives you the anchor rule, the dates that matter in 2026, a five-step routine, wording you can paste into a confirmation, and an honest note on where Tutafy helps and where it does not yet.

Why a lesson "at 6 pm" drifts

A lesson drifts when the two sides of it follow different clock rules. Take a Tuesday lesson fixed at 6 pm in London. In the week of 19 October 2026 London is on British Summer Time (UTC+1), so 6 pm there is 5 pm UTC, which is 1 pm in New York (UTC-4) and midnight in Ho Chi Minh City (UTC+7). On 25 October the UK goes back to Greenwich Mean Time (UTC+0). The London lesson is still at 6 pm, but it is now 6 pm UTC, 2 pm in New York, which is still on summer time for another week, and 1 am in Ho Chi Minh City. On 1 November New York goes back too, and its student is on 1 pm again.

Nobody did anything wrong in that example, and every calendar app converted the times correctly. The trouble is that a human agreed "6 pm" and a different human is holding a clock that now says 2 pm. This is where most late arrivals and no-shows from a time zone mix-up come from, and it is why a cancellation policy alone does not fix them. The cause is a rule, not a person.

The 2026 clock-change calendar for tutors

These are the changes that move most online tutoring lessons. Check your own country's official source for the exact hour, and check the dates again each year, because a few governments change their rules.

Five steps that stop a repeating lesson drifting

Each step answers one way a lesson goes wrong. Do them in order when you start with a student, and repeat the last one twice a year.

1. Pick the anchor: the clock that cannot move

Ask whose day is least flexible. A ten-year-old who has a lesson at 5 pm after school, or an adult with a fixed shift, anchors to their own clock. A tutor with a full week of back-to-back students may do better anchoring to their own. When both sides can bend, anchor to your own, because you are the one person in every lesson and your calendar then keeps the same shape all year. Write the anchor in the student's profile so it is not remembered, it is recorded.

2. Fix the slot in that zone, by city

Store the time as "Tuesday 6:00 pm Europe/London", not as "Tuesday, 7 hours behind me". The Europe/London style names come from the IANA time zone database that calendars and phones use, and they carry the clock-change rules with them. A label like "GMT+1" does not: it stays at plus one hour all year while London does not. In Google Calendar you can set the event's own time zone, and show a second time zone down the side of your week, which turns the translation into something you can see.

3. Show both times in every message

A reader checks the number that belongs to their own clock and ignores the other. So give them both, in the same sentence, with the city. Use this shape for a confirmation, a reminder and a reschedule:

• Tuesday 3 November, 6:00 pm London (GMT) / 1:00 pm New York (EST). The lesson is fixed on London time.
• Moved to Thursday 5 November, 7:30 pm Sydney (AEDT) / 8:30 am London (GMT), same day for both of us.
• Reminder: your lesson starts in 24 hours, tomorrow at 9:00 am Ho Chi Minh City (UTC+7). Your calendar shows it in your own time zone.

4. Name the dates when a clock changes

Two weeks before a change that affects a student, send one message with the date and what moves: "Europe goes back on 25 October. Your lesson stays at 6 pm London time, so it is 1 am for me and 2 pm for you in New York that week." It takes one minute per student and removes the most common argument in this part of the job, the one that starts with "but you said 2 pm".

5. Re-check twice a year, not when it breaks

Put two reminders in your own calendar: the week before the first clock change of spring and the week before the last one in autumn. On each date, open next week's lessons, read the times in your own zone and the student's, and fix any that landed on the wrong side of the change. The whole check takes ten minutes for twenty students.

Group classes across three zones

A group class on Zoom or Google Meet with learners in London, New York and Hanoi has no single "usual" time, and the anchor rule still works: pick one zone, publish the class time in all three, and say which one is fixed. Pick the anchor that suits the most people. With a London anchor the class moves on the Hanoi clock twice a year and on the New York clock four times (8 March, 29 March, 25 October and 1 November in 2026). With a Hanoi anchor the Hanoi clock never moves, and London and New York each move twice, on their own change days. Say which one you chose on the class page in one sentence, because someone will always ask.

What Tutafy does with time zones, and what it does not

Tutafy's booking page shows each free time in the tutor's time zone with the visitor's own time under it, worked out from the browser, so a student in London booking a tutor in Ho Chi Minh City sees "8:00 PM" with "1:00 PM yours" under it rather than doing the sum. In your Settings, check that your own time zone is right before you share your link, because every time on the page is read from it. The Find me a tutor form also shows times in the visitor's zone once the browser reports it, and lets the visitor change it.

Here is an honest limit as of this writing. When you create a repeating lesson in Tutafy (weekly, every two weeks or monthly), each lesson is placed a fixed number of 24-hour days after the first, 7, 14 or 30. That is exact elapsed time, not the same clock time, so if your own clock changes inside the series, the lessons after the change move by an hour on the wall clock. Monthly means every 30 days, not the same date each month. The fix is simple: create a series in blocks that end before the next clock change, or check and edit the first lesson after the change. We would rather say so than let you find out in November.

Mistakes that cause most time zone no-shows

• Writing "GMT+1" instead of a city, so the label stays the same while the clock changes.
• Converting only your own side. The student reads the number meant for you.
• Sending the reminder in the tutor's time zone when the student lives in another.
• Assuming everyone in a country changes the same day. Arizona, Saskatchewan and parts of Australia follow different rules from their neighbours.
• Moving a lesson "one hour earlier" by hand after a change, then forgetting which side moved.
• Leaving the anchor unrecorded, so after three months nobody remembers whose clock the lesson follows.

If you are also tightening your cancellation rules, the sensible place to say "times are fixed on the anchor clock and I will name the dates when it changes" is the same short policy document. We cover that in the guide to cancellation policies, and the reminder habits in the guide to stopping no-shows, both linked below.
