Then you might find the link below useful. It will allow you to download a simple Excel spreadsheet I created to track the dates when I restring my guitars. Just enter the names of your various guitars in column A, and then start filling in columns C, D, E, etc. each time you restring that particular guitar. The number of days since the most recent restringing will appear in column B (the gray shaded one). I think you'll find that as you accumulate guitars (and if you hang out here, you WILL accumulate guitars), this is a handy way to keep track of which was restrung when. I filled in a sample line with a couple of dates to show how it works. Just delete or type over the contents of those cells to re-use that row. Of course, you'll need MS Excel to use this tool.
