About This Feature

Overview

DAYS is a built-in date function in WPS Spreadsheet that returns the number of days between two dates. Its syntax is DAYS(end_date, start_date). It is useful for attendance tracking, project duration calculations, contract date checks, and other spreadsheet scenarios that require date differences.

Core tasks include:

  • Insert the DAYS function from the Insert Function dialog when you want guided parameter entry.
  • Type =DAYS(...) directly in a cell or in the formula bar for faster formula entry.
  • Review the function syntax and parameter details before finalizing a formula.
