    I mean in Vancuver BC longest summer, official daylight is 5:05am, but twilight is 4:23am. Toronto daylight in longest summer day starts about 5:35 (twilight at 5am) The twilight here is super bright. East coast gets more daylight in winter I think

      The eastern part of a time zone has earlier sunrise/sunset than the western part of that same time zone. A little past Detroit would have Vancouver times.

        Maybe winter, but if you check longest Sumner day as a common point, Vancouver has earlier sunrise by 25-30 minutes, and earlier twilight by 40…compared to detroit. I have lived in both areas . It is also not just about the time zone positions laterally because the sun shadow is at an angle compared to longitude due to precession angle I assume. If you lookup sunshadow animations you will see what I mean.
