Hey mr. Barnett, Unfortunately, I do need an accurate calculation, because the calculation will run 2 ways. From and to our calendar. I have no problem creating my own datefunctions if I have some idea on how PHP handles the current ones as a template. Then I can figure out the rest for myself. Would you know where I might find more info regarding this in stead?
