Power of five

This is obvious, but it only came to me this week.

My review process is to recall a three-day window finishing on the current day of the week for each week from when I began this process.

So today being Sunday, I've whizzed through the memory tags pinned to my mental calendar for Fridays, Saturdays and Sundays. I say the date to myself as I do so to associate this with the image.

I've just realised the obvious: adding five to the date of Sunday, gives me the date of the following Friday (except when it comes to the next month, of course).

I've been doing things much more cumbersomely since I began this method.
