Use Siri to Find Events in Other Apps
You can set up your iPhone so that Siri suggests events it locates in the Mail app, Messages app, and Safari, such as meeting times or reservations. Then you can opt to add them to the Calendar app. For example, if an email reads, “How about dinner tonight at 8 p.m.? Or would you prefer Wednesday around 7 p.m.?” the Mail app underlines these times to make it easy to add one or both to your calendar. You need to enable Siri for this function, though. Here’s how. Now Siri flags events that occur in these apps on the iPhone by underlining them so you can add them to your Calendar app.
How to Add Email Events to Your Calendar
To add email events to the Calendar app using the date or time flagged in the email, follow these steps.
How to Add Messages Events to Calendar
If you frequently receive appointment reminders via the Messages app, you can add the events to your calendar directly from the Messages app, just as you can from an email.
Add Appointments From Safari to Calendar
In a similar manner to the Mail and Messages apps, confirmed listings in the Safari browser—such as confirmation for plane reservations or hotel dates that you make on a web page—give you the option to click them in the browser and add them to your calendar.
