Frequently asked questions
- How is a "month" defined here, since months vary in length?
- As an average month (365.2425 days ÷ 12 ≈ 30.44 days), since calendar months aren't a fixed duration. For anything requiring calendar-exact month arithmetic, this average won't be precise — it's meant for rough duration conversion, not calendar math.
