which is the best way to write the date of birth?
Date of Birth: 25th August 1990
25th of August 1990
It depends on where you will send the info.
Your way is good enough,although the Americans do month/date/year in numerical way like 08/25/1990.
Just to throw in a wrinkle: In an American resume, CV, you would NEVER enter your birthdate. Age is prohibited to ask about and should not be provided by the job seeker.
I know that wasn't the question, but if you're doing this for an US company, just OMIT IT!
