The deadline date to register your UAS with the FAA is February 19, 2016.
If your aircraft weighs more than 0.55 lbs. (250 g) and less than 55 lbs. (25 kg), and you’ve been flying it outdoors or plan to fly it outdoors for hobby or recreation, federal law requires you to register by this Friday, February 19, 2016. http://www.faa.gov/uas/registration/
