The Ugears Date Navigator is an interesting mechanical calendar with a beautiful Steampunk planetary mechanism inside and your daily companion to keep track of your adventure and activities in 2017-2044. It also has a sweet faint scent of wood. Just set the year and month you need and find out what day of the week it is going to be. Never get lost in time again! The Date Navigator helps to identify the day of the week for any date from 2017 to 2044. It's assembled without glue like all UGEARS models.
