Day 213

It has been 213 days since I arrived in Ann Arbor.

I feel that day time is long.
It hasn't been dark until 8 p.m.

The US has 4 time zones.
However it seems having a time difference of more than 4 hours,
at least in a world map.
This means that
there are different times of sunset in a time zone.
That is my hypothesis,
but I haven't prove it yet.
