Finally, you wake up from a coma

Question

You can barely open your eyes when a doctor walks up to you:

You are a lucky one. Not many people have survived an accident like this. Only a handful of neurosurgeons are able to perform such an intervention, which is why you were transferred here. It is still 2017 and after 237 days in a coma, life will now slowly come back to normal. Welcome back.

[Doctor walks out of the hospital room]

While still trying to make sense of the situation, alone in the room, you take a glance at the clock on the wall. You swear you remember that the last time you checked before the accident was later on the same day.

What was the date of the accident?

Answer 1

The date of the accident is

March 11 2017

Explanation

You look at the clock on the day of the accident, March 11 (11/3/2017) and wake up after being transferred to another country with another date format, 237 days later on November 3 (11/3/2017).
