- not provided
- Scenario
- Writing a DATE formula that references another cell to construct a new date.
- Observed behavior
- The formula returns a syntax error due to incorrect argument separators, or evaluates to an incorrect date/#NUM! error because a full date is passed instead of a year.
Check your computer's regional settings to confirm whether commas or semicolons are used as list separators, and verify the exact data format currently stored in the referenced cell.
Adjust Formula Separators for Regional Settings
Change your formula argument separators from commas to semicolons if your system regional settings use a comma as a decimal separator.
In many regions, the comma is used as a decimal mark (e.g., 3,14 instead of 3.14). Consequently, spreadsheet software requires a semicolon (;) to separate function arguments to avoid syntax confusion.
Click on the cell displaying the formula parse error and place your cursor in the formula bar at the top of the screen.
Delete the commas separating your arguments and replace them with semicolons. For example, change =DATE(A$3,1,1) to =DATE(A$3;1;1).
Press the Enter key. The formula should now calculate properly without triggering a syntax error.
Extract the Year from a Full Date Reference
Use the YEAR function when your referenced cell contains a complete date rather than just a 4-digit year value.
Easily Manage Formulas and Regional Settings in WPS Office
WPS Spreadsheet provides a highly compatible and intuitive platform for complex data calculations. It supports all standard Excel formulas, including DATE, and intelligently handles syntax prompts to prevent regional separator errors.
- 1. Open your workbook: Launch WPS Spreadsheet and open the file where you need to calculate dates.
- 2. Start typing the formula: Select a cell and type =DATE(. WPS will display a tooltip showing the correct argument separator (comma or semicolon) based on your system settings.
- 3. Input the arguments: Enter your year, month, and day values or cell references following the exact syntax shown in the helpful tooltip.
- 4. Complete the calculation: Press Enter. WPS Spreadsheet will instantly calculate and format the result as a standard date.
Frequently Asked Questions
Why does Excel show a formula parse error when I use commas?
This occurs if your computer's regional settings use the comma as a decimal separator (common in many European countries). In this case, semicolons are required to separate formula arguments so the software doesn't confuse them with decimal points.
Can I change my default formula separator back to a comma?
Yes. On Windows, open the Control Panel, go to Region > Additional settings, and change the 'List separator' character back to a comma. You may also need to change your 'Decimal symbol' to a period.
What happens if the DATE function gets a serial number instead of a year?
Spreadsheets store dates as sequential serial numbers (e.g., January 1, 2024 is stored as 45292). If you pass a cell containing a full date directly into the year argument of the DATE function, it reads this massive number and returns a #NUM! error or an incorrect year. Using the YEAR() function fixes this by extracting the 4-digit year.
Does WPS Spreadsheet use the same DATE formula as Excel?
Yes, WPS Spreadsheet is fully compatible with Excel formulas. The syntax, logic, and handling of internal date serial numbers are identical, ensuring your spreadsheets work seamlessly across both platforms.
