The MONTH Function in Excel: Extracting Months from Dates
The MONTH function in Excel is a powerful tool for extracting the month from a given date. It returns a number between 1 (January) and 12 (December), making it invaluable for date analysis, financial reporting, and data segmentation.
Syntax and Usage
The basic syntax of the MONTH function is:
MONTH(serial_number)Where serial_number is the date from which you want to extract the month. This date should be in a format that Excel recognizes as valid.
Examples
- If cell A1 contains the date
2023-10-05, the formula=MONTH(A1)will return 10. - Using
=MONTH(DATE(2023, 10, 5))will also return 10.
Common Use Cases
The MONTH function is versatile and can be applied in various scenarios:
- Financial Reporting: Group transactions by month for analysis.
- Project Management: Determine the month of project milestones.
- Sales Analysis: Identify monthly trends and seasonality.

- Inventory Management: Track monthly restocking patterns.
Practical Applications
Here are some specific examples of how the MONTH function can be used:
- Financial Reporting:
=MONTH(A2)where A2 contains “2023-10-15” returns 10. - Project Management:
=MONTH(B2)where B2 contains “2023-05-20” returns 5. - Sales Analysis:
