Hello there! I am stuck with the following expression. From what I have seen and asked a Polish person, the structure of ''happy + number'', doesn't exist per se. You do have happy Christmas/anniversary, but when it comes to something more specific it seems unnatural in Polish or it just doesn't have a fixed way. Let's consider the following context. There are two friends who are very happy and get along very well, one of them wants to say something like ''happy 6th month'', as a celebration. The same thing could apply to co-workers if one of them wants to congratulate the other for being working for 6 months in the company. Szczęśliwych sześciu miesięcy seems to be too unnatural, so, what do you guys propose for such cases? Z góry dziękuję!
