Calculate the number of working days between two dates. Useful for project planning, payroll calculations, and deadline estimations in business and administrative contexts.
Number of working days: 0
A working days calculator helps you determine the exact number of business days between two dates, excluding weekends and focusing only on Monday through Friday. This essential tool is crucial for project planning, payroll calculations, deadline management, and various business operations where you need to count only actual work days rather than calendar days.
Whether you're managing project timelines, calculating employee work schedules, or determining business deadlines, our working days calculator provides accurate results instantly.
Note: This calculator considers Monday through Friday as working days, excluding weekends (Saturdays and Sundays). Public holidays are not taken into account in this basic calculation.
The basic formula for calculating working days is:
1Working Days = Total Days - Weekend Days

The calculator uses the following steps to compute the number of working days:
While working days (Monday to Friday) are commonly used, there are alternatives depending on the specific needs:
The concept of working days has evolved alongside labor laws and business practices. In many countries, the five-day work week became standard in the 20th century, particularly after Henry Ford adopted it in 1926. This shift created the need for accurate working day calculations in various fields.
As global business practices have evolved, so too have the methods for calculating working days, especially with the advent of computers and specialized software. Today, working day calculations are integral to project management methodologies, financial models, and HR systems worldwide.
Here are some code examples to calculate working days between two dates:
1from datetime import datetime, timedelta
2
3def calculate_working_days(start_date, end_date):
4 current_date = start_date
5 working_days = 0
6
7 while current_date <= end_date:
8 if current_date.weekday() < 5: # Monday = 0, Friday = 4
9 working_days += 1
10 current_date += timedelta(days=1)
11
12 return working_days
13
14## Example usage:
15start = datetime(2023, 5, 1)
16end = datetime(2023, 5, 31)
17working_days = calculate_working_days(start, end)
18print(f"Working days between {start.date()} and {end.date()}: {working_days}")
191function calculateWorkingDays(startDate, endDate) {
2 let currentDate = new Date(startDate);
3 let workingDays = 0;
4
5 while (currentDate <= endDate) {
6 if (currentDate.getDay() !== 0 && currentDate.getDay() !== 6) {
7 workingDays++;
8 }
9 currentDate.setDate(currentDate.getDate() + 1);
10 }
11
12 return workingDays;
13}

15// Example usage:
16const start = new Date('2023-05-01');
17const end = new Date('2023-05-31');
18const workingDays = calculateWorkingDays(start, end);
19console.log(`Working days between ${start.toISOString().split('T')[0]} and ${end.toISOString().split('T')[0]}: ${workingDays}`);

25These examples demonstrate how to calculate working days between two dates in various programming languages. You can adapt these functions to your specific needs or integrate them into larger systems for time and project management.
Working days are Monday through Friday, excluding weekends (Saturday and Sunday). Most businesses operate on this 5-day schedule, making working days calculations essential for project planning and business operations.
To calculate working days, subtract weekend days from the total calendar days between your start and end dates. The formula is: Working Days = Total Days - Weekend Days.
No, this basic working days calculator only excludes weekends. Public holidays are not automatically excluded. For business days calculations that include holiday exclusions, you'd need a more advanced calculator.
Working days typically exclude only weekends, while business days exclude both weekends and public holidays. Business days provide a more precise count for official business operations.
This calculator uses the standard Monday-Friday work week. Some countries have different working days (like Sunday-Thursday in Middle Eastern countries), which would require a customized calculation.
The working days calculator remains accurate for any date range, whether days, months, or years. It properly accounts for leap years and varying month lengths.
Working days calculations are essential for:
If your start date falls on a weekend, it won't be counted as a working day. The calculator will begin counting from the next Monday.
