What are you supposed to get when you click:
Feb 13,2017 AT 8:05AM - 5 years ago -if you have a google account with a calendar you can add the event to your own google calendar (some people use the google calendar as a diary some don’t)
the calendar is a file which is normally with email clients like outlook or outlook express to add the calendar to that email client and when that event comes up they get a reminder- customers either use it or they don’t but it just makes it easier for customers to remember to go to the event
