Capability Summary	DAYS360 can be entered directly in a spreadsheet cell to calculate the number of days between two dates based on a 360-day year, with support for parameters and cell references.	Excel provides the DAYS360 function and returns the number of days between two dates based on a 360-day year, with U.S. and European methods.	Google Sheets provides the DAYS360 function and returns the difference between two dates based on a 360-day year, with an optional method argument.	Notion formulas support date calculations such as `dateBetween()`, but the help center does not describe a built-in DAYS360-equivalent spreadsheet function.	Adobe Acrobat help content focuses on PDF editing, forms, and document workflows rather than spreadsheet functions like DAYS360.
WPS Advantages	Advantage: You can enter the formula directly in a worksheet cell and use it with existing spreadsheet data for day-count calculations.	Compared with WPS: Excel offers the same function name and similar syntax, so formula habits transfer easily between spreadsheet workflows.	Compared with WPS: Google Sheets also supports DAYS360, but its workflow is centered on browser-based spreadsheets.	Compared with WPS: Notion supports date formulas in databases, but it does not use the same worksheet-cell formula model for this function.	Compared with WPS: Adobe Acrobat provides document and form tools rather than a spreadsheet function workflow for 360-day date calculations.
