Is the twelfth of June correct way to spell?

No, "twelfth of June" is not the correct way to spell the date.

The correct way to spell it is June 12th or the 12th of June.

Here's why:

* Ordinal Numbers: When referring to dates, we use ordinal numbers (first, second, third, etc.) for the day. So, instead of "twelfth," we use "12th."

* Month First: In most English-speaking countries, the month comes before the day.
