A collection of events and dates for nature photography, wildlife, astronomy, critical thinking, and anything else that strikes my fancy. Feel free to contact me through this page if you feel something should be added.

NOTE: If an event’s start and end times are “11:59 PM,” just ignore it – it’s a fudge around the display options. I have not bothered to list peak times for moon phases. Also note that eclipse times are listed in UTC, and must be converted to your local time.
