Frequently Asked Questions
How do I calculate working days between two dates?
Enter your start and end dates in the calculator above. It
automatically counts weekdays (Mon-Fri) and optionally excludes holidays. The result shows total
working/business days between the dates.
What is a business day vs calendar day?
Calendar days include all days (weekends, holidays).
Business days (working days) are only weekdays, typically excluding public holidays. "5
business days" ≠ 5 calendar days.
How do I add business days to a date?
Use the Add Days tab. Enter your start date and number of working
days. The calculator skips weekends and holidays to find the target date. Example: Jan 1 + 10 working
days = Jan 15.
Are weekends included in business days?
No. Standard business days are Monday through Friday only.
Saturdays and Sundays are excluded. Some industries (retail, healthcare) may define it differently—check
with your organization.
How many working days are in 2026?
2026 has 251 working days in the US (excluding 10 federal holidays
falling on weekdays). This equals about 50.2 work weeks. Varies by country and which holidays you
observe.
How many working days in a month?
Typically 20-23 working days per month. It varies: some months
have more weekends, some have holidays. Average is ~21 working days/month or ~252 per year.
What holidays are excluded?
This calculator uses US Federal Holidays: New Year's, MLK Day,
Presidents Day, Memorial Day, Juneteenth, Independence Day, Labor Day, Columbus Day, Veterans Day,
Thanksgiving, Christmas.
Can I include Saturdays as working days?
Yes! Check the "Include Saturday" option. This is useful for
industries that work 6-day weeks. You can also include Sundays if needed.
How do I calculate a deadline in business days?
Use Add Days: enter today's date and the number of business days.
Example: "deliver within 5 business days" starting Monday Jan 6 = delivery by Monday Jan 13 (skipping
weekend).
Do different countries have different working days?
Yes! Many Middle Eastern countries use Sunday-Thursday as work
week. Holidays vary widely. India, China, UK all have different holiday calendars. This calculator uses
US defaults.
What about half-day holidays?
This calculator counts whole days only. Half-days (Christmas Eve, etc.) are counted
as full working days unless they're listed as holidays. Adjust manually for half-days if needed.
How do I calculate time off between dates?
Use Days Between to count working days. This shows how many
vacation/PTO days you'd use. Example: Dec 23-27 vacation = 3 working days (excluding Christmas holiday).
What is the difference between workday and business day?
They're typically the same: Monday-Friday excluding holidays. Some
contexts use "workday" for any day you personally work, while "business day" refers to standard industry
days.
How do banks calculate business days?
Banks use banking days: Monday-Friday excluding federal holidays.
ACH transfers typically take 1-3 business days. Weekends and holidays don't count for processing.
Can I exclude custom holidays?
This calculator uses preset US Federal Holidays. For custom holidays, note which
dates apply and manually adjust. Future versions may support custom holiday lists.
How accurate is this calculator?
Calculations use US Federal Holidays and standard Mon-Fri weeks.
For legal/financial deadlines, verify with official sources. State and local holidays may differ.
What does "within 5 business days" mean?
Count 5 weekdays from the start date, skipping weekends and holidays. If sent
Monday, 5 business days = the following Monday. If sent Friday, it's the next Friday.
