Q:

Right sentence for keep a date in mind

A friend will get married and she made a banner with "Save the date" expression, expecting her friends to memorize/annotate the marriage date. The sentence doesn't feels right to me, but I could not think in any other option. What sentence could be more appropriated for this case?

A:

Sending out "Save the Date" invitations or announcements is a common thing to do before a wedding, at least in America. Your friend was correct.
Do a google search of "save the date origin" for much more information.
