When buying eggs, the date in which the eggs were collected is displayed on the package. However, instead of a regularly formatted date, it is displayed as the number of days from the beginning of the year. For example, January 1st is 1, February 1st is 32, and so on.

This simple calculator helps you determine the freshness of your eggs before you buy them, by telling you today's day number. If today is 161, and your eggs were collected on 158, they are 3 days old.

You can click on the date or the number, respectively, to change them to any value.

Cheers!
