Gmail Add-on

This adds an icon to your Gmail mail editor as shown here, indicated by the red arrows on a computer (left image) or Android phone (right image):

When you click on this while typing an email, a list of various versions of today's date (before and after sunset) is displayed. When you select one, it is inserted into your email.

Holy Days and Feasts are displayed if they fall on the day being displayed.


You can also move to the next day or the next month(s) to see those dates. This is a great way to get the details for the upcoming Feast.
