Today on episode 6 of the Alexa Cast, I explain how you can have Alexa read your calendar (Alexa, what’s on my calendar) but you can also have Alexa add an event to your calendar (Alexa, add an event to my calendar). You can also try these:
Alexa, when is my next event?
Alexa, what’s on my calendar tomorrow at 9 p.m.?
Alexa, what’s on my calendar Saturday?
Alexa, add “Buy groceries” to my calendar for Saturday, February 27 at 3 p.m.
It appears the length is set to the default length of your appointments. Also it appears she can't delete things from your calendar.
This is all setup by linking your Calendar in the Alexa App
