A one-decade rosary is a short version of the Rosary that consists of a set of ten beads, which are used to count off a series of prayers. In short, it's 1/5 of a full Rosary, which is made up of five full decades.
You can use this shortened Rosary to simply pray one decade, or pray a full Rosary by repeating the prayers around the one-decade Rosary five times. It's also known as a "finger rosary" because it is small enough to be held in the hand and used to count off the prayers on the fingers. A Decade a Day will be a perfect way to begin to integrate the Rosary into your life. Most people who pray the Rosary pray it throughout the day and do one Decade at a time when they are able to. You could start a decade while going to work, when you have a break, before bed, whenever your work is repetitive. With your family all together because as you know "A Family that prays together, stays together."
Starting with a Decade a Day will unlock the Power of the Rosary in your life and once unlocked, God-willing never be closed by anyone again. Always do your best to at least pray a Decade a Day and you will get closer to Jesus through Mary.
