Description
startingDay indicates which day is considered the first day of the week.
The first week of the year is the first week that contains four or more days of that year. For example,
if you select 1 (Sunday) as the starting day, then January 1 must be on Sunday, Monday, Tuesday,
or Wednesday for that week to be the first week of the fiscal year. If you select 2 (Monday) as the
starting day, then January 1 must be on Monday, Tuesday, Wednesday, or Thursday for that week to
be the first week of the fiscal year.
It is possible, using this function, that dates in a particular year will be returned as the 53rd week of
the previous year. For example, if in 2008 you selected Sunday (1) as the starting date, then
January 1, 2, or 3 in 2009 would occur in week 53 of fiscal year 2008 (in 2009, January 1 is on a
Thursday). The first day of fiscal year 2009 would be on Sunday, January 4, because you selected
Sunday (1) as the starting day.
Important To avoid errors when using dates, always use four-digit years. For more information
about how FileMaker Pro handles two-digit dates, see Conversion of dates with two-digit years.
