In English we don't use the word "congratulate" for holidays, birthdays or anniversaries.  We say, "Happy New Year", "Happy Birthday", "Happy Anniversary", but!  "Merry Christmas".  We can make complete sentences, such as, "I wish (I'd like to wish) you a Happy New Year."  "I wish you a very Happy Birthday."  "I wish you a very happy 10th wedding anniversary."  "May you have a very Merry Christmas."

The word "congratulate" and "congratulations" are used to acknowledge or express gladness at someone's good fortune or achievement.  Examples:  "You just got married?  Allow me to congratulate you!"   "You were just promoted?  Wow, congratulations!"
