Try this
- Write the day, full date, local time and exact meeting point in one message.
- Ask for confirmation if the plan requires it. If using a calendar invitation, verify the person can access it and that time-zone conversion has not changed the intended hour.
A worked example
“Saturday the twelfth, two o’clock, at the museum entrance.”
An invented example to adapt, not a real exchange or a script you have to follow.
Before you leave it here
Avoid relying on a calendar invitation alone when one person does not use that calendar.
