The "official" or regular weekend of the Potomac River Convention is the first Sunday in April and the Saturday before (and in some years, the Friday evening before), except when Easter falls on this weekend (see below). Note that the weekend defined in this manner may not always equate with the "first (full) weekend in April."
According to a policy set by Potomac River Convention organizers several years ago, if the regular weekend (defined above) coincides with Easter weekend, the Convention will be held on another nearby weekend to be decided on a case by case basis. The next years in which a conflict with Easter will occur are 2010 and 2015. In contrast, if the regular weekend falls on Palm Sunday, the Convention will take place as usual on its regular weekend. This will happen next in 2012.
Recent experience has shown that when Palm Sunday falls on the same weekend as the Potomac River Convention, there is little or no reduction in convention attendance, because most of the attendees are not committed church choir members. This was certainly the case in 2004 and 2007, when the convention turnout was excellent, particularly on Saturday all day and Sunday afternoon.
