Hi everyone! I'm here! Let's talk!
Welcome to italki Olesya!
Nothing to correct!
You might want to write the date differently, because for days from 1 to 12 it can be confusing.
America remembers 9/11 but to them it is the September 11th, in UK 9/11 would be the 9th of November.
(Obviously there aren't 29 months...)
