Remarks

Validity of the date

The validity of the date passed as parameter is checked. A message is displayed if the date is invalid. You can check the validity of a date using DateValid. The date storage format allows you to store dates from 01/01/0001 to 12/31/9999.
The calculations performed on dates by the WLanguage functions or by the WLanguage properties are accurate from January 1st 1583.

Date format

<Date type>.ToString is used to format a date returned by IntegerToDate or DateSys. The result can be assigned to a text control, for example.
To get the date in another format, use Right, Left, Middle, etc.

Special case: <Format> is not specified

The language options specified for dates in the project description are used if no specific format is defined.
To display the linguistic options of the project:
  1. Open the project description: on the "Project" pane, in the "Project" group, click "Description".
  2. Select the "Language" tab.
For example:
  • if the project uses the linguistic options of Windows for the dates, the days of the week and the months will start with an Uppercase character on a computer running Windows in English.
  • if the project uses specific parameters for the dates for one or more languages (custom name of the day or month, etc.), these parameters will be taken into account for the specified language.
