About This Feature

Overview

WEEKNUM is a date and time function in WPS Spreadsheet on Windows that returns the week number of a date within a year.

Core tasks include:

  • Insert WEEKNUM from the Insert Function dialog when you want to search for the function name and fill in arguments step by step.
  • Type =WEEKNUM(...) directly in a cell or in the formula bar for faster daily use and fill-down workflows.
  • Review the syntax WEEKNUM(serial_number, [return_type]) and argument meanings before choosing the week-start rule.

Common use cases include weekly reports, attendance summaries, and sales cycle analysis.

It helps convert dates into week numbers more quickly and reduces manual counting errors in spreadsheet work.

In WPS, you can use either a dialog-based entry path or direct formula input, depending on your workflow.
