Hey there!
Your Events Calendar Pro license key will expire on March 20, 2017. Your Community Events license key will expire about a month later, on April 14, 2017.
Both are “Personal” licenses. If you upgrade either license (or both), then that specific license that you upgrade will also have its expiration “renewed” and pushed out another year.
So, if you upgrade the Events Calendar Pro personal license to business today, July 20, 2016, then it will not expire again until July 20, 2017.
I hope this helps! You can upgrade any time by using the “Upgrade to:” buttons found in http://theeventscalendar.com/license-keys
Cheers!
George
