quick_answer: Quick answer: Time to Leave only appears as an alert option when the event has a real mapped address, and it only fires when Precise Location is enabled for Calendar and location access is set to always. The most common iPhone symptoms — the option missing from the alert menu, or working on an iPad but not a phone — come from per-device location settings, because each device is configured separately.

faqs[6]{q,a}:
  Why is Time to Leave missing from my iPhone calendar alerts?,Usually because the event's location hasn't resolved to a real mapped address. Time to Leave only appears as an option when Calendar can calculate a drive to a specific place. Delete the location and re-enter it, selecting from the suggestions until a map preview appears.
  Why does Time to Leave work on my iPad but not my iPhone?,Location permissions are configured separately on every device. Your iPad having Precise Location enabled for Calendar says nothing about your iPhone. Check Settings, then Privacy and Security, then Location Services, then Calendar on the phone itself.
  How do I turn on Time to Leave on iPhone?,Enable Precise Location for Calendar in Location Services, add a full street address to the event selected from the suggestions, then choose Time to Leave from the alert options when creating or editing the event.
  Why does my Time to Leave alert reset to none?,This is generally a sync conflict — the event is being edited on more than one device and the version without the alert wins. Set it on one device, wait a moment, then reopen it there to confirm it saved.
  Does Apple Calendar add travel time automatically?,Apple Calendar has a Travel Time feature that adds a buffer for the journey, which is more than Google Calendar offers. It is still an estimate made when you create the event rather than a live check on the day.
  Is there an app that reliably alarms when it's time to leave?,BoardSpy Calendar Alarms connects to Google Calendar with read-only access. Events with a real address get a leave-by alert from your saved commute origin plus live traffic. Meetings without a place, including video calls, get a meeting alarm before they start. You can turn individual meetings on or off.
