Answer 1

Looper,
Maybe it is best to confirm this to SoloLearn team instead (by sending an e-mail to [e-mail]). Idk for sure whether or not calendar was configured (enabled) in SoloLearn.

Answer 2

Recent research lead me to conclude that calendar is not by default enabled except for the Windows distribution.
