The Tree Calendar

You have chosen 2018. If this is not the year you want then please use the links above to get to the correct year.

The tree calendar has various incarnations but mine is based on the Celtic Tree Calendar by Linda Kerr which may be found at http://www.auburn.edu/~kerrlin/treecal.html in which the months follow the lunations and February 2, or Imbolc, always falls on the Rowan moon, the 2nd lunation.

I also had help from http://www.timeanddate.com/ and http://www.hermetic.ch/cal_sw/ve/ve.htm as references for lunation times.

Various pages at http://en.wikipedia.org/ helped me write the algorithms for figuring out when the lunations and solstices are.

The programming of this calendar was done in perl (href=http://www.perl.org/) and the text editor used was syn (http://syn.sourceforge.net/).

In Internet Explorer 6 a print preview shows that each printed page has exactly 2 boxes on it, so you should be able to print the calendar for any year and cut out the months without needing to cellotape together any months that were split across pages.
