If you receive an email that includes a date and time, the Mail app on your iPhone or iPad can recognize it as an appointment request. Here's how to create a calendar event from an email.

The Mail app on iPhone and iPad includes Siri Intelligence technology which can automatically analyze a message on your device to find an appointment.

This feature works with both natural language, and the traditional date and time structure. For example, if you get an email that says, "Let's meet for lunch this Saturday at 1 p.m.," the Mail app recognizes the day of the week, the date, and time.

To create a calendar event, open the email with the appointment request in the Mail app on your iPhone or iPad. You see the date and time are underlined. You might also see a banner at the top of the email that says, "Siri found 1 event."

Tap "Add" in the banner or tap the underlined text.

Tap on Underlined text or Add button to create an event from Mail app

From the menu, tap "Create Event."

Tap on Create Event from popup menu in Mail app

The event creation screen slides up in the Mail app. If you tapped "Add," you'll see that Siri added a subject, and selected the time and date for you. If you tapped the underlined text, only the data from that text is added to the event.

You can add a location, change the duration, set alerts, send an invite to the event, or further edit the info any way you like.

When you're satisfied with the event info, tap "Add." This creates the event in your calendar, and you're taken back to the email.

Fill in the calendar event details and tap on Add button to save the event

To make sure the event is on your calendar, open the Calendar app, select the week view, and then navigate to the day of the event.

Open Calendar app to check the created event

If you use the Mail app to schedule work and/or personal events, this little trick can save you a lot of time.

Just tap the underlined text. Or, even better, let Siri analyze the whole message, and then just tap "Add" to create an event from the information in the email.
