Entering Days of the Week, Months, and Day-of-the-Week Lists:

Some of the functions in this plugin take days of the week or months as arguments. Where you see a dow parameter, you should supply a day of the week. Day names may be abbreviated to the first three letters of their English names: MON, TUE, and so on. If Windows is set up for a non-English locale, you can also use the local abbreviated day names as reported by the @IDOW function. Localized day names must match all characters returned by @IDOW, including any accents or other diacriticals. Finally, you may use numbers: 1 for Monday, 2 for Tuesday, and so on. (Sunday may be specified as either 0 or 7.)

A month parameter may be entered as an English month name (only the first three letters are significant): JAN, FEB, MAR, and so on. In a non-English locale, you may instead use local abbreviated month names as reported by @MONTHNAME[n,3]. Localized month names must match all characters, including any accents or diacriticals. You can also use numbers: 1 for January, 2 for February, and so on.

A few of the functions in this plugin accept lists of days of the week. Wherever you see a dowmask parameter, you can enter:

•   One or more days of the week, separated with spaces or semicolons: MON WED FRI for Mondays, Wednesdays, and Fridays
•   a range, two days separated by a dash: TUE-FRI for Tuesdays, Wednesdays, Thursdays, and Fridays
•   the word WEEKDAYS (equivalent to MON-FRI) or WEEKENDS (equivalent to SAT-SUN)

If you type an exclamation point before the list, the meaning is inverted: !TUE THU means all days except for Tuesdays and Thursdays. You can use local day names or digits in a dowmask if you wish.
