Features
Our Serial Date Converter provides a simple way to convert between Excel serial dates (numeric representations) and human-readable dates. Excel stores dates as serial numbers where January 1, 1900 is day 1, making calculations easier but less intuitive for humans.
This tool supports bidirectional conversion - enter a serial number to see the corresponding date, or input a date to get its serial representation. Results are shown in both your local timezone and UTC for maximum compatibility. Perfect for spreadsheet analysis, data processing, and understanding legacy date formats.
