59th year (2021-22) * 57th year (2018-20)

54th year (2017) * 53rd year (2016)

52nd year (2015) * 51st year (2014)

50th year (2013) * 49th year (2012)

48th year (2011) * 47th year (2009-2010)

45th year (2008) * 44th year (2006-2007)

42nd year (2005) * 38th year (2002)

My numbering scheme is confusing even to me...

When I write "50th year (2013)", I mean the following: the document, although written around my 50th birthday in January 2014, covers the prior year when I was in fact 49 but in my 50th year. Hope that's made it less clear for everyone.
