I know there has been a lot of talk in this section recently about getting things prepared for the birds in cold weather. One of the preparations people have been doing is setting up timers for their coop lights (lots of great threads going on that, by the way! ). I thought I would add a couple links to sunrise-sunset calendars so that you can use these as a reference when making your timer plans. http://www.sunrisesunset.com/custom_srss_calendar.asp This one is for the U.S. http://aa.usno.navy.mil/data/docs/RS_OneYear.php This works for any location worldwide.
