Saying your birthday

If someone asks “Tanjōbi wa nan-nichi desu ka” [誕生日は何日ですか]? He's asking what your birthday is. Now let's see how to correctly answer this question.

You need to put the day of the month after the month itself. If your birthday was March 4th, for example, you would say:

The other forms we are going to present now are variations that add or take away some of these words, making the sentence more formal or more informal. See some examples:

The addition of the word chamaimasu made the sentence much more formal and polite.

おたおめ Otaome

Otaome is a very short and informal abbreviation, often used by young people or in informal settings such as online text messages on the internet.

In the example above we added the person's age, congratulating them for reaching that age. Age is represented by circles, while the suffix [歳] refers to years of age.
