Business Day Calculator to Calculate Working Days Between Dates

Business Day Calculator Sign

This free online calculator will calculate the number business days between two dates, or calculate an ending date based on a specified number of business days to add or subtract to or from a starting date.

Plus, unlike other working days calculators, this calculator will not only let you choose which days of the week you want to be counted as business days, but it also allows you to indicate which, if any, holidays you would like excluded from the count.

This customization feature means you can also use the calculator to count work days only (working days calculator), or any other types of events that are counted based on which days of the week they reoccur.

If you would like to calculate the years, days, weeks, hours, and minutes between two dates, please visit the Date Difference Calculator.

Adjust Calculator Width:

Move the slider to left and right to adjust the calculator width. Note that the Help and Tools panel will be hidden when the calculator is too wide to fit both on the screen. Moving the slider to the left will bring the instructions and tools panel back into view.

Also note that some calculators will reformat to accommodate the screen size as you make the calculator wider or narrower. If the calculator is narrow, columns of entry rows will be converted to a vertical entry form, whereas a wider calculator will display columns of entry rows, and the entry fields will be smaller in size ... since they will not need to be "thumb friendly".

Show/Hide Popup Keypads:

Select Show or Hide to show or hide the popup keypad icons located next to numeric entry fields. These are generally only needed for mobile devices that don't have decimal points in their numeric keypads. So if you are on a desktop, you may find the calculator to be more user-friendly and less cluttered without them.

Stick/Unstick Tools:

Select Stick or Unstick to stick or unstick the help and tools panel. Selecting "Stick" will keep the panel in view while scrolling the calculator vertically. If you find that annoying, select "Unstick" to keep the panel in a stationary position.

If the tools panel becomes "Unstuck" on its own, try clicking "Unstick" and then "Stick" to re-stick the panel.
