Complete Guide: How to Calculate Saturdays and Sundays in Excel
Calculating weekends (Saturdays and Sundays) between two dates is a common requirement in Excel for payroll processing, project management, and business analytics. This comprehensive guide will walk you through multiple methods to accurately count weekend days in Excel, including formulas for different Excel versions and practical applications.
Why Count Weekend Days in Excel?
Understanding how to count weekend days is essential for:
- Calculating business days for project timelines
- Payroll processing (identifying weekend work)
- Resource planning and scheduling
- Financial calculations involving weekend processing
- Data analysis requiring weekend/weekday separation
Method 1: Using NETWORKDAYS Function (Excel 2007 and Later)
The NETWORKDAYS function is the most straightforward method for counting weekend days between two dates. Here’s how it works:
Returns the number of workdays between two dates. To get weekend days, subtract this from total days.
Complete formula to count weekend days:
Example: To count weekends between January 1, 2023 and January 31, 2023:
Result: 10 weekend days (5 Saturdays + 5 Sundays)
Method 2: Using WEEKDAY Function (Works in All Excel Versions)
For older Excel versions or more control, use the WEEKDAY function with array formulas:
This formula:
- Creates an array of all dates between start and end
- Uses WEEKDAY to determine day of week (1=Sunday, 7=Saturday)
- Counts how many times these values appear
Method 3: Counting Saturdays and Sundays Separately
To count Saturdays and Sundays individually:
Sundays: =SUMPRODUCT(–(WEEKDAY(ROW(INDIRECT(A1 & “:” & B1)))={1}))
Where A1 contains start date and B1 contains end date.
Method 4: Using Power Query (Excel 2016 and Later)
For large datasets, Power Query provides an efficient solution:
- Load your data into Power Query Editor
- Add a custom column with formula: Date.DayOfWeek([YourDateColumn], Day.Sunday) = 0 or Date.DayOfWeek([YourDateColumn], Day.Sunday) = 6
- This creates a TRUE/FALSE column for weekends
- Filter for TRUE values to get weekend dates
Comparison of Excel Weekend Calculation Methods
| Method | Excel Version | Pros | Cons | Best For |
|---|---|---|---|---|
| NETWORKDAYS | 2007+ | Simple, built-in function | Requires subtraction from total days | Quick calculations |
| WEEKDAY Array | All versions | Works everywhere, precise control | More complex formula | Legacy systems |
| Power Query | 2016+ | Handles large datasets | Requires Power Query knowledge | Big data analysis |
| VBA Macro | All versions | Most flexible, can be automated | Requires macro security | Automated reports |
Practical Applications of Weekend Calculations
Understanding weekend calculations enables powerful business applications:
1. Payroll Processing
Many companies pay premium rates for weekend work. Use these formulas to:
- Automatically calculate weekend hours
- Apply different pay rates for weekends
- Generate reports for compliance
2. Project Management
Accurate weekend counting helps with:
- Realistic project timelines (excluding weekends)
- Resource allocation planning
- Gantt chart creation
3. Business Analytics
Separating weekend data reveals important patterns:
- Weekend vs weekday sales performance
- Customer behavior differences
- Operational efficiency metrics

Counting Weekends in a Month
To count all weekends in a specific month:
Common Errors and Solutions
| Error | Cause | Solution |
|---|---|---|
| #VALUE! error | Non-date values in formula | Ensure all inputs are valid dates |
| Incorrect count | Not accounting for inclusive/exclusive end date | Add/subtract 1 from total days as needed |
| Formula not updating | Automatic calculation disabled | Press F9 or enable automatic calculation |
| Wrong weekend days | Different weekend definition (e.g., Friday-Saturday) | Adjust WEEKDAY parameters or use custom function |
Automating Weekend Calculations with VBA
For repetitive tasks, create a custom VBA function:
Dim DaysCount As Long
Dim CurrentDate As Date
DaysCount = 0
For CurrentDate = StartDate To EndDate
If Weekday(CurrentDate, vbSunday) = 1 Or Weekday(CurrentDate, vbSunday) = 7 Then
DaysCount = DaysCount + 1
End If
Next CurrentDate
CountWeekends = DaysCount
End Function
Use in Excel as: =CountWeekends(A1,B1)
