Screensaver that displays day of week, date and time in largest font. Has an option to also dispaly time until (or since) any chosen date and time. Not restricted by unix date which is only valid between Jan 1, 1970 and sometime in 2037. Options for seconds, 24 hour clock, and world clock (GMT).
I invented this program to help my mother who has failing short term memory and kept asking what day it was. It didn't work, she could not remember to look at the computer screen.

I added the delta time feature to show time until retirement. Young children like to have the chosen date as Christmas.
