// lines like this one beginning with double slashes are comments
// the basic form of each tab delimted data entry line is:
// YEAR <tab> MONTH <tab> DAY <tab> MODIFIER <tab> CLOSED <tab> NAME <tab> COMMENT <cr>
//
// if YEAR=0 then the holiday occurs on this date every year
// if MODIFIER=0 then MONTH & DAY represent an absolute date
// if MODIFIER<>0 then DAY encodes the nth WEEKDAY of MONTH and MODIFIER=WEEKDAY
// where WEEKDAY = (Sunday=1,Monday=2,...,Saturday=7)
// e.g. 0	11	4	5	1	represents the 4th thursday in Nov every year
// if CLOSED=0 this holiday is disabled
// if CLOSED=1 the RadOnc dept is closed for patient treatments
// if CLOSED=2 the RadOnc dept is open for patient treatments
