First, get the sunrise/set times for Washington D.C. These look correct.
(www.timeanddate.com report 06:12 and 19:59 for sunrise/set today)
>>> sun = Sun(38.8895, -77.0353)
>>> sun.get_local_sunrise_time(dt)
datetime.datetime(2020, 4, 29, 6, 12, tzinfo=tzlocal())
>>> sun.get_local_sunset_time(dt)
datetime.datetime(2020, 4, 29, 19, 59, tzinfo=tzlocal())
>>> sun.get_sunrise_time(dt)
datetime.datetime(2020, 4, 29, 10, 12, tzinfo=tzutc())
>>> sun.get_sunset_time(dt)
datetime.datetime(2020, 4, 29, 23, 59, tzinfo=tzutc())
Now change the latitude 1 degree north. A small change is expected, but notice that the sunset time jumps back one day now that the sunset time goes beyond 20:00 local time (00:00 UTC)
>>> sun = Sun(39.8895, -77.0353)
>>> sun.get_local_sunrise_time(dt)
datetime.datetime(2020, 4, 29, 6, 10, tzinfo=tzlocal())
>>> sun.get_local_sunset_time(dt)
datetime.datetime(2020, 4, 28, 20, 1, tzinfo=tzlocal()) <=== Wrong, should be the 29th
>>> sun.get_sunrise_time(dt)
datetime.datetime(2020, 4, 29, 10, 10, tzinfo=tzutc())
>>> sun.get_sunset_time(dt)
datetime.datetime(2020, 4, 29, 0, 1, tzinfo=tzutc()) <==== Wrong, should be the 30th
