🔸 You are 1 year old at birth (not 0)

🔸 Age increases every January 1st (not on your birthday)

🔸 Your Kazoedoshi age is ${kazoedoshi} — ${kazoedoshi - westernAge} year${kazoedoshi - westernAge !== 1 ? 's' : ''} more than Western age

📝 Note: Japan officially switched to Western age system in 1902, but Kazoedoshi is still used in traditional ceremonies, New Year celebrations, and some Buddhist rituals.
