Editing DateCode

= The Sharp Date Code = An easy to use, compact code for dates is invaluable to sort files chronologically, and saves precious room on crowded Excel listings and DVD titles. == How It Works == Extending conventional hex code, a single character represents months ranging from Jan [1] through August [8], September [9], October [A], November [B], and December [C]. Similarly, the days of the month range from [1] through 31 [V]. To create files, checks, DVDs, etc. for this century, the codes range from Jan 1 2000 [0011] through December 31 2099 [99CV]. I routinely add a date suffix to file names, e.g. revisions of the same file might be called: [study063U], [study063V], [study0641]. So the file names will sort chronologically in systems lacking accompanying creation dates. This code is very easy to create using three mnemonics: hex F [15], and the PK disease [25], [20]. I also know 30 and 31 are [U] and [V]. It turns out that converting back to conventional dates is needed much less frequently than creating codes since the compact chronological sort meets most of my needs. --JoeSharp == Discussion == If you need to refer to historical or future dates, how about this? * Magna Carta signed: C156F * US Declaration of Independence: H7674 * US Emancipation Proclamation: I6311 * Black Tuesday: J29AT * Hiroshima Atomic Bomb: J4586 * My 200th birthday: L656R So with the addition of only one character for the century, you can represent a range of 32 centuries past and future, from the year 1 through the year 3199. Of course, you can still make the first character "understood", just as the "20" is understood in today's date when written 3/28/06. BCE dates and dates from 3200 CE forward are left as an exercise for the gentle reader. -- ["Ron Hale-Evans"] [[DateTime(2006-03-28T18:40:31Z)]]
