Try this
- Check the next appointment in both locations using the actual date, not a remembered hour difference.
- Send one proposed time with both local equivalents and update the calendar only after agreement.
A worked example
“Our old slot now lands during your commute. Would moving it an hour later in my calendar work better?”
An invented example to adapt, not a real exchange or a script you have to follow.
Before you leave it here
Verify the next occurrence, especially if the calendar repeats automatically. Correct the schedule without treating either person’s mistaken conversion as a broken commitment.
