Calculators
How the count works
The calculator counts whole days from the start date to the end date. “Include end date” adds one day — useful for things like hotel nights versus days of a trip. Business days exclude Saturdays and Sundays but not public holidays, which vary by province.
Frequently asked questions
How do I calculate my exact age?
Enter your date of birth; the calculator shows years, months and days, plus your age in total months, weeks and days.
Does it handle leap years?
Yes. Dates are calculated with the real calendar, including 29 February.
Are public holidays excluded from business days?
No — only Saturdays and Sundays are excluded, because holidays differ by province and employer.
