Diary hack :)

Hi!

This might be useful to you if you have unused diaries from the past which you want to use, rather than waste.
Not many people know this, but there is a pattern to the cycle of dates. What this means, is that on a pattern of 6 and 11 years, the dates of a specific year repeat (except for leap years). So, for example, all the dates from 2001 match the dates of 2007 and 2018 too!
See the table below for illustration of this. I've done from 2000 to 2020. (I've left out 2000, 2004, 2008, 2010, 2012, 2016 and 2020 because either they have no repeat in the 20 years I have done, or no repeat at all).

So, if you have an old diary, you may be able to use it again! for example, a diary from 2001 or 2007 you haven't used, you can use it again in 2018!
I'm doing this with a filofax mini 2009 diary refill I got in a filofax I bought used from ebay, I will use it in 2015! All I did was tipex out the year!
Unfortunately this doesn't work for 2012 because it is a leap year, but in 2013 you could use a diary from 2002!

Hope this helps!

  2. I keep coming back to this and finally printed out your chart. I got two new binders from the UK today and they had both 2011 and 2012 inserts. Cool! I'll just hang onto them.

  3. thanks Terri! but be warned, I don't think 2012 repeats because it is a leap year and leap years are strange! but I may be wrong...

  4. Hi TPS! I received my BEAUTIFUL Sunflower Piazza from the Great German sale today, and it has both 2011 and 2012 diaries in it. So just to be clear; the 2011 diary can be used again in 2022? :)

    Thanks,
    The mathematic mastermind Liisa! :D
