okay first of all y'all don't even know how to count you go from 0 to 1 and that's one same with the first year as well it starts with zero then 24 hours pass it becomes a day then 6 months pass it becomes half a year another becomes one but the entire year counts as one and a decade doesn't mean add it means a whole group of ten it's like saying a year is adding one year so essentially a year doesn't pass on year 1 it passes in year 2 with that logic we call it 1 year because it's a whole group of 1 year duh a group of ten is a decade a group of 100 is a century etc basically learn to count
