If you want your old equipment to work past the year 2000, use this simple expedient:
If you use this table to select the year, then (with 2 exceptions*) the days of the week and the days of the month will be right, although the year number will be wrong:
|Actual Year||Try this first||If that doesn't work, use|
|2000||1972||1994 (Jan ... Feb)* 1995 (Mar ... Dec)|
|2004||1976||1998 (Jan ... Feb)* 1999 (Mar ... Dec)|
|Actual Year||Year to use||Procedure to find year|
|2009 ... 2027||1981 ... 1999||Subtract 28 from the year number.|
|2028 ... 2099||1972 ... 1999||Repeatedly subtract 28 until the result is less than 2028.
Then use the entries above to get the correct year.
* The day number will be wrong for February 29 for these years. If you had to choose this option, then your computer's calendar has no way to represent this date correctly. It will display March 1 before you change to the other year, and must be changed to February 28 when you change to the other year on that date. The day of the week will be correct for both dates.
With this table, you can keep that obsolete DOS computer, and your old VCR, camcorder, stereo, oven, watch, or other appliance working with a minimum of fuss. Please print it out for your future reference.
