Today is the Singles' day, so I want to say something like "Today is my day. I accept your congratulations". Sure, it's some kind of a joke.
Could you correct me, please, if I'm wrong: 今天我的日子！ 接受你们的祝贺。
Is this sounds ok? Or it's gonna sound strange for chinese people?
今天是我的日子 is not something a Chinese person would say, because it is a direct translation of an English colloquial phrase.
If you want to express your happiness on this day, you can say:
光棍节真是为我设计的 (Single's Day was created for me).
光棍节了真开心， 都来祝贺我啊~ (I am so happy that it is Single's Day. Everyone congratulate me).
These are informal ways of talking, which may have better results if you want to make a joke :)
今天是我的日子！
今天是我 接受你们的祝贺的 日子！ 。(the relative clause should be placed before the noun "日子"
However. “Today is my day” is a common English expression that means “Today is my lucky day” or “today is the day I success”. It would be "今天是我走運的一天" (today is my lucky day) or "今天是我吐氣揚眉的日子"(today is the day I success) in Chinese language.
"Singles' day is a day for me," is "單身日是為我而設的日子" or simply "單身日是我的日子" in Chinese.
今天是我XX的日子.
今天是我大喜的日子 (for wedding).
今天是我的幸运日.
