Capability Summary	In WPS Spreadsheet, `WEEKNUM` returns the week number for a date and can be used with parameters for different week-start rules.	Excel provides `WEEKNUM(serial_number,[return_type])` with two week numbering systems and multiple return types.	Google Sheets provides `WEEKNUM(date, [type])` for week-number calculation with different start-day and system options.	Notion provides database formulas, and `week()` returns the ISO week of a date, but it is not a cell-based spreadsheet function.	Adobe Acrobat focuses on PDF form calculations and field rules rather than a spreadsheet-style `WEEKNUM` function system.
WPS Advantages	Advantage: You can enter the function directly in worksheet cells and continue using references, nested formulas, and result organization in the same sheet.	Compared with WPS: Excel also provides a full spreadsheet formula system with a similar function name and parameter structure.	Compared with WPS: Google Sheets supports a similar week-number function, but it is mainly used in an online spreadsheet environment.	Compared with WPS: Notion formulas are designed for database properties rather than cell-by-cell spreadsheet editing.	Compared with WPS: Adobe calculation features are designed for PDF forms, so they are not a direct replacement for spreadsheet date functions.

Overall Conclusion
If your work focuses on spreadsheet-based date analysis, weekly grouping, and follow-up formulas, WPS offers a familiar worksheet workflow for week-number calculation.
