Capability Summary	Use WEEKNUM in a formula field in a multidimensional table to return the week number of a specified date, and combine it with other functions in nested formulas.	Excel provides the WEEKNUM function to return the week number for a specific date, with support for different week-start settings and numbering systems.	Google Sheets provides the WEEKNUM function to return the week number of the year for a given date, with an optional type parameter.	Notion supports database formulas based on properties and functions, but it is not a cell-based spreadsheet function environment.	Adobe Acrobat mainly supports calculated fields in PDF forms for dynamic form calculations, rather than spreadsheet-style WEEKNUM functions.
WPS Advantages	Advantage: WEEKNUM can be used directly in record-level formula fields in multidimensional tables, which fits workflows where week values need to stay attached to business records as data changes.	Compared with WPS: Excel uses WEEKNUM as a worksheet cell function for spreadsheet calculations.	Compared with WPS: Google Sheets uses WEEKNUM in online spreadsheet cells.	Compared with WPS: Notion is centered on database property formulas, so week-based logic usually needs to be assembled from broader date functions.	Compared with WPS: Adobe focuses on PDF form workflows rather than table analysis scenarios.

Overall Conclusion
If your work is centered on weekly analysis inside record-based multidimensional tables, WEEKNUM in WPS is well suited for writing week values directly into formula fields and keeping them updated with the data. Excel and Google Sheets are more direct for traditional spreadsheet cell formulas, while Notion and Adobe are weaker equivalents for this specific use case.
