Key Takeaways

Solutions to Common Problems

1. Check Function Syntax

Ensure you’re using the correct syntax for the WORKDAY.INTL function:
excel
WORKDAY.INTL(start_date, days, [weekend], [holidays])

  • start_date: The starting date.
  • days: A number of workdays to add.
  • weekend: Optional. Specify which days are considered as weekends.
  • holidays: Optional. A range of cells that contain holiday dates.

2. Verify Date Formats

Make sure that your start_date is in a proper date format. Excel might not recognize text formatted as dates. Convert dates to ensure they’re compatible.

3. Check for Compatibility Issues

The WORKDAY.INTL function is available in Excel 2010 and later. If you’re using an older version, this function will not work.

If you’re trying to use WORKDAY.INTL within an array formula, ensure that you’re using CTRL + SHIFT + ENTER instead of just ENTER.

3. Check for file corruption

Sometimes files can become corrupted. Save your workbook under a new name, which might resolve underlying issues.
