Rated 4 out of 5 stars

Actually the Add-on is not doing what the name suggest :-) BirhtDAY - the Add-on requires that a year is given in the extended contact information otherwise the birthday is not shown in the calendar. Would be nice to relax this since the year of birth is often unlikely to know.

Four out of five stars! The Add-on is just working, the suggested extensions to the contact information make sense. Good work, keep going!

This review is for a previous version of the add-on (0.2.7). 

I admit that it\'d be nice if one had not to specify the year, but in Lightning, some year has to be specified. Maybe I could set the year to 0 if no year was specified and not display the age in this case...
