I was trying to do something with Coletto Calendar, but it just did not let me continue to use it. Some time later, I received a notification from Yahoo:
To our valued customers...some reasons why Coletto Calendar did not work... Therefore, the Coletto Calendar application will no longer be offered by the end of 2016, January.
Is it a formal way to write the date this way? But it made me think I could continue to use it until the end of 2016 in the first place.
