Many app creators find the Calendar section very useful. Sometimes it is even the main section of some apps. Here are some examples of use. 

Calendar sections for a employee communication app 

The company Dali Corp decided to use the Calendar section for two major purposes: to communicate about internal company events such as workshops, afterworks or even open days of the company.
A second Calendar section was created to share the company's road map with employees, so that everyone knows the company's current and future projects and deadlines.

In the details of the events, we find when necessary, the address of the event and an itinerary button.

A Calendar section for a festival app

Here we are at the heart of the matter. The Piu Piu festival uses the Calendar section as the main section of its app, the objective being to communicate about the festival program.

In the details of the event, we find the address of the event, the date of course, but also a button to buy a ticket, a description of the event, a link to the website of the artists, a call button, an email button and a button for directions. 
Also the possibility to bookmark and share this event.
