Why count days?

Days are the smallest unit of time most people think about in terms of life progress. 10,000 days old is a milestone many celebrate — it falls at approximately 27 years and 4.5 months. 5,000 days is around age 13.7. 20,000 days arrives around age 54.8.

For new parents, tracking a baby's age in days during the first months helps monitor development milestones. For people in recovery, counting sober days is a meaningful and powerful practice. For anyone, discovering that you've lived exactly 12,345 days or are one week away from your 10,000-day mark is one of life's small delights.
