Help me solve my English problem.

I'm just used to adding.11June 2008 when reading.

This statement is definitely wrong. In English, the date is month, day and year, so it should be June 2008 1 1 day.

So the correct expression of your sentence should be that I am going to the store on June 19. By the way, let me tell you about the usage.

You can search the website yourself, and I'll tell you something about that year.

Before ordinal number, the emphasis is on times, order, seconds, etc.

But this year, the month and the day are just dates, not a day in a month, so there is no need to write, but I am used to reading in spoken English.
