Are you brave enough?



Happy Calendar is a unique calendar, where every day there is one good simple and lovely deed is written, which makes people’s day happier and motivates us to do small good deeds, which are very important. For example, the deed can be to thank someone, to give a hug or just to smile. Small things, which we easily forget.


I’m Rudolf from Estonia. I grew up in large family with not so many possibilities so I had to make everything myself. At the age of 13 I started Happy Calendar. I saw that there are so many unhappy people arround me. I was thinking that it’s due the bad weather or lack of sun or just because the life is hard. I thought, when every people makes at least one small good deed every single day, I can make people happier. The idea is simple, if you do something good to others it spreads out and soon everybody sees more positivity on their daily actions. Join the Happy Calendar movement and do good on every day.
