Why " i can't change date of the concert " is wrong?

[HanneHallum0]

Why is it wrong when I write I can not

[Jim8161]

Don’t use can not when you mean cannot. The only time you’re likely to see can not written as separate words is when the word “can” happens to precede some other phrase that happens to start with “not”
