Try this
- Compare the next few weekends and choose the actual first occurrence.
- Label the rhythm as a preference rather than an automatic reservation. Confirm later dates around real commitments instead of assuming alternation guarantees availability.
A worked example
“Would every other Sunday be more realistic for our cooking afternoon?”
An invented example to adapt, not a real exchange or a script you have to follow.
Before you leave it here
Put the next occurrence in the calendar only after confirming it still fits.
