The main idea of the Collective Birthday Calendar is to calculate the common birthdate of many people together. The program is able to calculate the average birthday of 2-30 people collectively, up to the 2000th birthday.

Let me quote the ancient philosopher, Democritus: „Life without celebrations is a long journey without rest.

I can highly recommend this new "Collective Birthday Calendar and I wish you good luck and many happy "collective" birthdays!
