About This Feature

Overview

DAYS360 is a built-in date and financial function in WPS Spreadsheet. It returns the number of days between two dates by using a 360-day year with 12 months of 30 days each.

Core tasks include:

  • Insert DAYS360 from the Insert Function dialog.
  • Enter =DAYS360(...) directly in a cell or in the formula bar.
  • Review the function syntax DAYS360(start_date, end_date, [method]) and its arguments.

This function is useful for worksheets that need a 360-day basis for payment periods, billing cycles, interest periods, and similar date calculations.
