Each date is represented by a serial number, which corresponds to the number of days that have elapsed since January 1, 1900. This underlying numerical representation allows for powerful date calculations and comparisons.
However, to ensure readability and clarity, Google Sheets provides various date formats that you can apply to your data. These formats dictate how the date is displayed, allowing you to customize the appearance according to your preferences or reporting requirements.
