A working day or business day is a day of week except public holidays.
Workingdays.ca calculates for you the number of working days and public holidays between two dates in Canada
(your office tools won't know them since they change every year)
.
Just pick up (or enter) start and end dates, the analysis will start automatically !
Use the blue circles shortcuts to change the dates quickly (add

or remove

one day/month/year).
Notice also that you can change the results (within the green left hand result panel

) and thus add any number (positive or negative) of working days to a given date. With the padlock icons you can decide if you want to add days to start date

or remove days from end date

.

Use the
setup screen, if in your company working days don't go from Monday to Friday or to select public holidays relevant to you.
