Have you ever wondered when was the exact 10 000 days after your birth? Or 1 000 weeks after your wedding? Or 100 months after you first met your wife?

All you need to do is just tell the main date - when event happened. And after that, magic happens:
# You will be able to track how many days are left till main event date;
# App will calculate all upcoming special events for the next 1 or 2 years;
# You will be able to check what famous people are celebrating their birthdays on any date during the year. More than 1000 current and historical celebrities added;
# Group events into categories and filter them with one swype;
# The event is repeating every year (e.g. birthday, public holiday, wedding anniversary, ...)? Datesbook will recalculate time left till the nearest next year's main event every time it passes.
# Never miss any important event in your life! Notifications the same day or 7 days before any event will remind you about it. Select it's time in a day yourself.
# Surprise everybody around knowing facts, nobody knows: "Congratulations, John! It's 20 000 days for you today!"
# Know the signs of Zodiac for all your friends and relatives;
# Celebrating 5th wedding anniversary? Did you know that this anniversary is "wooden anniversary"? No? No problem. This app will tell you about it.
# Do you have many Johns' in your friends' list? No problem. You can add your own picture (or icon) near every event!
