It annoys you again and again to consider only what day of the event is now that you have you just made out with someone, or do you want to surprise your girlfriend where you say it, to which she is born weekday. Or surprise your friends in which you call them for any case of the week.
Then upload this week down the computer. It calculates the corresponding date for each day of the week.
The computer funktionier with dates far into the future.
