How To Subtract Dates In Excel To Get Years

Subtract Dates in Excel to Get Years

Using the DATEDIF Function

To calculate the difference between two dates in years, use the DATEDIF function. The syntax is =DATEDIF(start_date, end_date, "y"). Ensure your start_date and end_date are in date format. The "y" parameter specifies the unit as years, returning the number of complete years between the two dates.

Calculating Age from Birthdate

For calculating age from a birthdate, combine the DATEDIF function with TODAY(). Use the formula =DATEDIF(birthdate, TODAY(), "y") to return a person's age in complete years from their birthdate to the current date.

Error Handling

When using the DATEDIF function, note that the "md" argument may yield inaccurate results. To ensure accuracy, use the "y" argument specifically for finding the difference in years.

Alternative Methods

While DATEDIF is the primary method, Excel also offers other functions for age-related calculations. The YEARFRAC and EDATE functions can be used for more complex date calculations involving years, but are not designed solely for calculating years as DATEDIF with the "y" argument does.

Excel vs Sourcetable: Streamlining Data Integration and Analysis

Excel, a traditional data management tool, requires users to perform manual data integration. In contrast, Sourcetable is a next-gen data integration tool that automatically consolidates data from multiple sources into a single interface, simplifying querying and analysis.

Sourcetable's AI copilot significantly enhances user experience by providing real-time assistance in formula creation, templating, and other data manipulation tasks. This intuitive feature facilitates a more accessible approach to high-level data manipulation, catering to users of all skill levels.

While Excel's Analyze Data feature allows basic natural language queries within its ecosystem, it falls short in automation and seamless data consolidation. Sourcetable's AI copilot propels it ahead by reducing the need for extensive user expertise and manual manipulation required in Excel, offering an integrated, user-friendly solution.

For organizations prioritizing efficient data handling and analysis, Sourcetable emerges as a more automated and user-friendly platform compared to Excel, enabling faster insights and better data-driven decisions.
