Found this on pinterest. I didn't go to the link but just search "Date Night" on pinterest and you'll find this picture.
She took 12 closable folders and labeled them one for each month.
Then they planned out a date for each month:
January - dinner and trip to desired destination
February - spa night at home
March - Rock climbing
April - themed dinner and sight seeing
May - "for your eyes only" date
June - Takeout, then playing card at the park
July - Slumberparty (games, food, movies.... and pillow fight!)
August - Golfing (real or putput)
September - Camping
October - Hunted House
Novemeber - Archery/Shooting range
December - Visit Christmas list
You can customize it to fit your way of living. :) Buy giftcards to stick in the envelopes so your dates are already pre-paid NO EXCUSES!
