Seasonal Retreats start on Friday and require a two-night stay until Sunday, however, you can register to stay for up to two weeks from the Friday start of the Seasonal Retreat, provided the Monastery will be open during the entire two weeks or does not have another commitment such as a Themed Retreat.  If the Monastery is not available, the registration calendar for the Seasonal Retreat will indicate in red those days that a Seasonal Retreat stay is not available.
