To calculate how many hours you've lived at 13 years old, multiply your age by the number of days in a year and then by the number of hours in a day. There are 365 days in a year, so for 13 years: 13 x 365 = 4,745 days. Then, multiply by 24 hours: 4,745 x 24 = 113,880 hours. If you want to be precise, consider any leap years within that period.
