About This Feature

Overview

DAYS360 is a date and financial calculation function in WPS Spreadsheets. It is used to calculate the number of days between two dates based on a 360-day year, making it useful for accounting-style date intervals, payment-cycle estimates, and standardized reporting.

In WPS, you can enter the formula directly in a cell, follow parameter prompts while building the formula, use references across worksheets, and let results update automatically when source data changes. This makes it practical for spreadsheet analysis, recurring reports, and finance-related worksheets.

Capability Summary	Use `DAYS360(start_date,end_date,[method])` in WPS Spreadsheets to calculate date differences, with parameter prompts, cross-worksheet references, nested formulas, and automatic recalculation.	Excel provides `DAYS360(start_date,end_date,[method])` to return the number of days between two dates based on a 360-day year.	Google Sheets provides `DAYS360(start_date, end_date, [method])` for date differences based on U.S. or European day-count rules.	Notion formulas support date functions such as `dateBetween()` for date differences, but they are database property formulas rather than spreadsheet cell functions.	Acrobat supports calculated PDF form fields and date field settings, but it does not provide a spreadsheet-style DAYS360 function.
WPS Advantages	Advantage: WPS keeps formula entry, references, and recalculation inside a spreadsheet workflow, which fits repeated table analysis and finance-oriented worksheets.	Compared with WPS: Excel has a directly corresponding DAYS360 function with similar syntax, so the usage pattern is close.	Compared with WPS: Google Sheets also includes DAYS360, but its notes emphasize numeric date handling and literal input rules.	Compared with WPS: Notion is better suited to database property formulas than cell-based spreadsheet editing.	Compared with WPS: Acrobat focuses on PDF form calculations instead of worksheet-based batch date analysis.
