MyDate is Date = "20011225"
DateToDayInAlpha(MyDate)      // Returns "Tuesday"
MyDate is Date = DateSys()

" " + DateToMonthInAlpha(MyDate) + " at " + ...
TimeToString(TimeSys(), "HH:MM:SS")

Syntax
<Result> = DateToDayInAlpha(<Date>)
<Result>: Character string
Day of the week that corresponds to the specified date: monday, tuesday, wednesday, thursday, friday, saturday, sunday.
Remark: The day of the week depends on the linguistic options specified for dates in the "Languages" tab of the project description (on the "Project" tab, in the "Project" group, click "Description"):
  • If the project uses the linguistic options of Windows for the dates, the day will be returned in the language of Windows.
  • If the project uses specific parameters for the dates (for one or more languages), the day returned will correspond to the one specified in the project description.
<Date>: Character string, Date or DateTime variable
Date to use. This date can correspond to:
  • a character string in YYYYMMDD format (YYYY corresponds to the year, MM to the month and DD to the day).
  • a character string in YYYYMMDDHHmmSSCC format (YYYY corresponds to the year, MM to the month, DD to the day, HH to hours, mm to minutes, SS to seconds and CC to hundredths of a second (use CCC for thousandths of a second)). In this case, only the date is taken into account.
  • a Date variable.
  • a DateTime variable. In this case, only the date is taken into account.
Remarks
The date storage format allows you to store dates from 01/01/0001 to 12/31/9999.
WLanguage functions and WLanguage properties make accurate calculations on dates from January 1st, 1583.
