A volunteer opportunity may be canceled due to a school closure, a field trip, or a holiday. You can dates and times from the schedule.
How?
After adding a Volunteering Task, go to the Volunteer Signup page and click the Block button next to the date/time slot that is not available.
You can block one date or a time range. To block a time range, select the start and end date.
