// NOTE 2 The first calendar week of a calendar year may include up

// calendar week of a calendar year may include up to three
// days from the following calendar year;
//
// NOTE 3 The time-interval formed by the week dates of a calendar
// year is not the same as the time-interval formed by the
// calendar dates or ordinal dates for the same year. For

//
// Sun 1995 Jan 1 is the 7th day of the 52nd week of 1994
