In response to the August Technology Q&A topic "Dating Problems, Part 3" (page 85), reader Daniel Warco, CPA, (controller for the Elizabeth Glaser Pediatric AIDS Foundation in Washington) sent me a better solution than the ones I had suggested. As a reminder, the Excel question involved converting two-digit-year, text-based numbers into four-digit-year, date-based numbers. I presented five possible solutions, all of which were fairly complicated. Daniel said that you can simply add 1 and then subtract 1 from the two-digit-year, text-based number and then apply four-digit-year date formatting to convert the number to a four-digit-year, date-based number, as pictured below.
This tip works because the process of adding 1 and then subtracting 1 converts the text-based date to a numeric-based date, and previously I did not know that. (Thanks, Daniel. I plan to teach this tip in my next Excel course, and I'll act as if I've known about it my entire life.)
