The way I translate dates into pegs is by translating the date to a 3-digit number and then use my 3-digit system. Although, any 3-digit system will of course do so the only potentially interesting part is the translation to a 3-digit number. To be able to easily tell which month and day in the month a peg is I use the translation ((month-1)*50+(day in month)) so seven of august would be since august is month 8: ((8-1)*50+7)=357. The reason I multiply with 50 instead of 100 which would make more sense is that there are too many months if I still want to keep it to 3-digit numbers. And although this isn’t a problem for me yet, I plan to place special year pegs at the beginning of each year so that I can tell which year a peg translates to since after more then a year the pegs for each date will start to repeat, but I will know which is which by knowing where in the journey they appear. For instance if I would like to know what happened 2008-03-24 I would look at the journey between the peg for 2008 and 2009 and find the peg for mars 24.
Every day I add yesterdays happening so today I will add the sixth of august and I use one loci/day so I basically add one new loci per day or sometimes I might think about several loci ahead.
So to give an example. First of July which was the day I started this happens to translate into Sherlock Holmes. And what I do is simply imagining Sherlock Holmes studying some boxes with a magnifier on top of which my brothers are standing. This is enough for me to remember that I sorted/cleaned out some old stuff and hanged out with my brothers that day. And all this is happening in one loci, actually the loci is not very important since I use the pegs to index myself easily. So basically I pick out key events and make them into images. Sometimes they are straight forward like my brothers, sometimes they are a bit more abstract, but the main thing as I see it is that I know what they represent.
Also, one thing that I didn’t mention is that I use Anki to schedule revisions although I completely rely on my memory and have no written account of what happened each day. So Anki basically just says “review this day” and I do and then press the remembered good button (or hard), but I do rely on me never forgetting a day which hasn’t happened yet, but I guess it could happen and it could also happen that one want to make sure that all details are there.
And finally, I would like to encourage anyone who thinks about starting this to just start it. I had this idea for some time before I started and always thought that I should start on the first of january or my birthday or any other special day, but finally come to the conclusion that it actually doesn’t really matter. There is no reason why you should start on such a day and especially if you use a system similiar to mine it wouldn’t complicate the date indexing.
