In 2012, I planned an elaborate surprise for my husband's 40th which included a 40-day countdown to his birthday. Every day for 40 days, I gave him a countdown card that had a special note along with a small gift or letter that was written by a close friend. On his actual birthday, he received a message (on a huge candy board) that explained what he would be doing on his 40th birthday. I posted an explanation and the result on this 40 Days to 40th Birthday post. Several people asked me for the birthday tags that I created for the event. As a result, I put together all the elements to save you time in planning.
