I just have this interest in numbers and what they represent, and the meaning behind it. Similar like names. As names represent a person, so numbers represent something more significant than the symbols. Related to years, here my collection through the ages 🙂
For example, number 12 is very popular and has significant meaning in the Bible. When Jairus pleaded with Jesus for his daughter that terminally ill, it’s mentioned that she was 12 years old. And on the way to the house to heal her, Jesus met a woman which has suffered chronic illness for 12 years. It seems the number 12 there has deeper meaning / insight to the whole story.
