US Naval Observatory Sunrise/Sunset Data: Blank Sunrise/Sunset Times?
I get a blank entry for May 03.


The Sun didn't set on Bovinia, New York on May 03 when time is expressed as Universal Time. Sunsets from May 04 to August 16 occur before sunrise. (Also note that August 16 has two sunsets.)

The solution is simple: Fill in the time zone. Ignoring daylight savings time, time in Bovinia New York is offset by 5 hours from UTC.

Another solution is to use a different website. There are better web services than the simple perl-based script used to generate that table.
