There is an astronomical calendar on the Sidereal Times website for 2015. I created it using Sky Events Calendar, but I’ve found an easier way to build an astronomical calendar that I would like to share.
The United State Naval Observatory provides a free downloadable version of their Astronomical Almanac in iCalendar 2.0 format that can be imported into any calendar program that uses this format such as iCal, Outlook and Google Calendar. This link will take you to their site. Under the “Recent and Upcoming Phenomena” box, there is link to download the “Diary of Phenomena” file. Import this file into your calendar software to create a new calendar of astronomical event for the year like those listed on Sidereal Times.
I hope you find the calendar useful.
