Per convention, the OpenMRS community generally does not conduct meetings or events on federal holidays recognized in the United States. For your convenience, a list of those holidays and their observed dates are listed below. When a holiday falls on a weekend, it is often observed on the Monday or Friday nearest to its date.
We also recommend checking https://www.timeanddate.com/holidays/ for a list of known international holidays (ordered by date) when scheduling an event.
When in doubt, please ask your meeting organizer.
