> Put them in the cupboard and wait for 128M to come back in vogue. Which > will be right after 1999 calendars are popular again ;-) You're in luck then !!!!!!!!!!!!! 1999 calendars will again work OK in 2010 for the full year (so you'll be able to sell them from late 2009). They next become useful again in 2016, but only from 1 January until 28 February, when the leap year puts them out of sync. Next after that is 2021 when they again work for the full year. ___________________ RULES Use 7 columns. Write leap years twice. (1st is 1 Jan - 28 Feb, 2nd is 29 Feb - 31 Dec) Periods in vertical alignment match. viz 99 00 00 01 02 03 04 04 05 06 07 08 08 09 10 11 12 12 13 14 15 16 16 17 18 19 20 20 21 22 23 24 24 25 26 27 28 28 ... Latter part of also 2004 worked - but that's history. I can't work out how to make this work for 128M RAM chips though :-(.
