[REBOL] Re: add/subtract with date!

From: allen:rebolforces at: 14-Nov-2000 18:47

Hi Tom, REBOL makes it exceptionally easy to do. . date: 14-Nov-2000 date/day: date/day + 10 print date 24-Nov-2000 date/month: date/month + 3 print date 24-Feb-2001 date: 14-Nov-2000 date/year: date/year - 1 print date 14-Nov-1999 Only thing to watch is a bug in month subtraction. It goes flaky if you subtract prior to January . (Hopefully will be fixed soon Feedback #4014) date: 14-Nov-2000 date/month: date/month - 12 print date 14-Mar-23845 But subtraction using days does not have this problem date: 14-Nov-2000 date/day: date/day - 366 print date 14-Nov-1999 ----- >

Have a look at the calendar style script on my Rebsite, you will find a comment in that script where I handle the bug. Cheers, Allen K
