Siri is deeply integrated — you can say "Hey Siri, schedule a dentist appointment for March 5 at 9 a.m." and it will add the event to Calendar.

If you switch between Google Calendar and Apple's iCalendar, you'll be glad to know you can share data between each service. Jack Wallen shows you how.

As daily life feels more familiar, apps from Apple and Google can keep you organized and get you to your in-person events on time.

While much of the setup for Calendars is done on iPhone, you can use Apple Watch to respond to invites, add a quick event, and get alerts to remind you when to leave for your next appointment.

With Apple's latest software update, iOS 13, you now have the ability to add attachments to calendar events on your iPhone.
