The US Naval Observatory provides a site where you can generate a table of the sunrises and sunsets of every day of the year for any town in the U. S. Take look at your town and decide whether you would prefer daylight time or standard time year round. Keep in mind that it gets dark roughly 1/2 hour after sunset and gets twilight roughly 1/2 hour before sunrise. All times are reported in standard time so just add an hour to consider a daylight time scenario.
