About
Find public holidays in your country or region, then calculate business days around them. BizDay combines a regional holiday calendar with a simple date calculator so you can check holiday dates, count working days, and work out deadlines.
PUBLIC HOLIDAYS IN 46 COUNTRIES
Browse 269 national and regional holiday calendars across 46 countries. Select a country and region to see the public holidays that apply there, with their dates and names. Regional differences matter: a holiday in one area may not apply in another. BizDay uses your selected holiday calendar when calculating business days.
COUNT BUSINESS DAYS BETWEEN DATES
Choose a start date and an end date. See three results together:
• Total days in the selected period
• Business days, accounting for the selected public holidays
• Non-business days, including weekends and applicable holidays
No need to count calendar squares or build a spreadsheet. Check the period before a deadline, delivery, payment, or planned time off.
ADD BUSINESS DAYS TO A DATE
Need to know the date 10, 20, or 30 business days after a starting date? Enter the number of days and BizDay finds the end date. You can also add total days or non-business days.
KEEP IMPORTANT DATES VISIBLE
Save a date range and set notifications for when the range starts or ends. Use this for a payment period, project milestone, or another date that matters to you.
