Review on 🕒 Large Display Digital Timer & Picture Frame: 9999-Day Retirement Countdown Clock with Changeable Photo - Perfect Gifts for Men or Women, Countdown to Vacation, Wedding, Christmas, Halloween, or Holiday by Karen Mabey

While you can set the current date and time and then the "end" date and time, which is the desired date of the event, you cannot to select the days you want the screen to read as far as I can tell. I had to count backwards from my retirement date, skipping weekends, holidays, and vacation days to figure out how many days I had left until retirement. From there you count those days on the calendar and you can put that date in the "End" date to have "XXX working days until retirement". Other than that, it's great. You can insert your own photo and you're good to go.
