Say I create an event starting at 2 pm and at a location that takes me 10 min to walk to. I also add the alert Time to leave as the only alert.

Then, I will get a reminder at 1:35 pm. But I want the reminder only at 1:50 pm, exactly "when I need to leave" (without setting the reminder manually to 1:50 pm, of course).

How can I achieve this?

I know that I can snooze the notification, which will make it reappear in 15 minutes. But, then I am distracted from whatever I'm doing 15 minutes too early. So it is not a solution.

Edit: I want the event to still be displayed as starting at 2 pm in my calendar.

Edit 2: Also assume that I do not know the travel time when I create the event. So the mechanism of Time to leave that adjusts flexible to my location is still necessary.

  • In apple maps how long does it say the route takes?

  • The 10 minutes in the example are computed by the Calendar application using Apple maps. For example the Calendar iOS notification reads It will take 10 minutes to get to [address] and in the top right it reads in 25m.

I think here is the answer,

  1. When you create the event, make sure that you enter the location of the meeting in the event. Like in image, where you can see the greyed out portion with a caption

enter image description here 2.

Add Location (let it get recognize the event through the map app in the background -- you do not have to do anything, this will happen automatically based on your internet speed, so just give it some time, and once you the location listed, select the desired location from the options or the nearby location.)


Once you do that, if you try to set your event time say 08:00PM-09:00PM. Automatically you calendar will recognize this event as a remote location and will prompt you differently like this,

Time to Leave

This will update you about the meeting at the right time accounting for your traffic and weather conditions.

Good Luck !


When creating an event, there is the Alert option where it can be set to one of several options including "none"...

However, based on your comment, just add 15mins to the leave time then it will alert you at the correct moment...

  • This seems to completely turn off the reminder. But I do want to be reminded when it's time to leave.

  • The question in the title is clear, what you really want is something else then... Confusing... Please edit your question.

  • What part of the question in the title is different from what I want?

  • The title asks to "turn that off" ... which was answered...

  • The question asks to turn off the "too early" reminder. Not all reminders. Hence it was not answered.

Manually enter the desired travel time in the appointment. This overrides the calculated time.

  • Thank you for your answer. Unfortunately, this requires me to know the travel time at time of event creation, and thereby would take away the whole benefit of the automatically location adjusting "when I need to leave". Hence, it's not a solution, but I have edited my question to make this clearer.

  • One of the problems is that the calculated time will never exactly line up with the actual time because digital routing still doesn’t exactly match real-world travel time. Jan 22 '19 at 18:58
  • Are you saying the reason Apple implemented a too early reminder is because it is a very risk-averse solution to take care of the uncertainties of actual vs. planned travel time?

  • Only Apple knows. I’d guess it’s simply inaccuracy with the current data and technology we have. Jan 22 '19 at 19:01
  • The iOS notification specifically displays both in 25m at the top corner and It will take 10m to get there in the body. So the data is there and relatively accurate. Even if the predicted and actual time are different, why would Apple not notify me correctly at the time I need to leave according to their estimates?
