# Dates in Excel Explained

Author:

I'll explain how dates in Excel work and then point you to many useful tutorials on how to use dates and also times in Excel.

## What is a Date in Excel?

Dates in Excel are actually just numbers that are formatted as dates.

If you take a date and select the cell and then set that cell's formatting to "General" it will look like this: Cell A1 has the "date" and cell A2 has that same date formatted as "General."

As you can see, Excel stores dates in this weird format, but, it's actually not that weird and makes handling dates a lot easier.  Excel stores dates as numbers.

The dates actually start at January 1, 1900, which is represented with a 1, and add one for each day since then.  So Feb 10, 2016 is 42,409 days since January 1, 1900.

Look at what happens when you format 1 as a date (it appears as the date 1/1/1900): ## Why Does this Matter?

The point to learning that dates are just numbers in Excel is because, then, you can more easily remember how to manage them.

Add a day to a date by adding 1. Add a week by adding 7. Cells A4 and A5 show the formulas entered in cells B4 and B5.

As you can see, storing dates as numbers makes dates easier to work with because we can use simple math to adjust them.
