Working Days Calculator — Accurate Business Timeline Planning for 2026
Calculate working days between any two dates. Excludes weekends and public holidays for 30+ countries. Essential for project management, payroll, and legal deadlines.
Why Working Days ≠ Calendar Days
A typical month has 30–31 calendar days but only 20–23 working days. Add public holidays, and that number drops further. For example, December 2026 in the US has only 21 working days (Christmas + New Year holidays), while March 2026 has 22.Working Days by Month (US, 2026)
| Month | Calendar Days | Working Days | Public Holidays |
|---|---|---|---|
| January | 31 | 21 | New Year, MLK Day |
| February | 28 | 19 | Presidents Day |
| July | 31 | 22 | Independence Day |
| December | 31 | 21 | Christmas, NY Eve |
Key Business Applications
1. Project Management
When a project has a 60-calendar-day deadline starting April 1, our calculator shows you exactly how many working days you have, accounting for Memorial Day and weekends. This prevents the common mistake of over-promising delivery timelines.2. Payroll & HR
Salaried employees are paid for working days, not calendar days. Accurate working day counts are essential for prorated salaries, overtime calculations, and leave balancing.3. Legal & Contractual Deadlines
Many contracts specify "business days" for notice periods, dispute resolution, and payment terms. Miscounting by even one day can void a contract or trigger penalties.4. International Business
Public holidays vary dramatically between countries. Our calculator supports 30+ countries including the USA, UK, Germany, France, and more.How to Use Working Days in Your Planning

What counts as a "working day"?
A working day is any day that is not a weekend (Saturday/Sunday) and not a public holiday. In some countries, Saturday is a half-working day — our calculator follows each country's standard.
How many working days are in 2026?
In the United States, 2026 has approximately 251 working days (365 days minus 104 weekend days minus 10 federal holidays). The exact number varies by country and state.
Does the calculator account for regional holidays?
Our calculator includes national public holidays for 30+ countries. Regional or state holidays may vary. Check our holiday calendar pages for detailed breakdowns.
How do I calculate working days for international teams?
Run the calculator separately for each team member's country. A project spanning the US and UK will have different working day counts because of different public holidays. Use our year comparison tool to see how holidays shift year-to-year.
