How does the TODAY function work in Excel?
In Excel, dates are basically received as serial numbers. In Windows, the standard date system is based on the year 1990. Based on this standard, January 1, 1990, is number 1. Also, dates are valid through 9999 which is equivalent to serial number 2,958,465.
In this example, the current date is March 9, 2016. We want to calculate the days from the current date before January 1, 2050.

= 54,789 – 42,438
The output can be seen in cell D5. This means there are approximately 12,351 days before January 1, 2050, when counted from March 9, 2016.
