One of the great features of the Amazon Echo is the ability to check your calendar events by simply saying:
“Alexa, when is my next event?”
“Alexa, what’s on my calendar?”
“Alexa, what’s on my calendar tomorrow at [time]?”
“Alexa, add an event to my calendar.”
To connect your calendar, go to Here (UK) Here (USA) or open the Alexa app on Android or iOS, then go to Settings > Calendar and select either Google, Microsoft or Apple. Log in to your account and authorize the connection. If you want, you can add multiple calendars, but you will only be able to add new events to one of the connected calendars.
