How to convert hours to years
Years = Hours ÷ 8,760
A day has 24 hours and a common year has 365 days, so a year has 24 × 365 = 8,760 hours. Leap years have 8,784 hours. If your hours span decades, dividing by the Gregorian average of 8,765.82 hours makes almost no difference: 100,000 hours is 11.42 years one way and 11.41 years the other.
Getting years, days and hours
- Divide the hours by 8,760 and keep the whole number. That is the number of years.
- Multiply those years by 8,760 and subtract the result from your hours.
- Divide what is left by 24. The whole number is days, and the remainder is hours.
Worked examples
235,000 hours
235,000 ÷ 8,760 = 26.83 years. The whole years are 26, and 26 × 8,760 = 227,760, which leaves 7,240 hours. 7,240 ÷ 24 = 301 days with 16 hours left over.
Answer: 26 years, 301 days and 16 hours.
15,542 hours
15,542 ÷ 8,760 = 1.77 years. One year is 8,760 hours, leaving 6,782 hours, which is 282 days and 14 hours.
Answer: 1 year, 282 days and 14 hours, or about 7.5 years of full-time work.
10,000 hours of practice
10,000 hours is 1.14 calendar years of round-the-clock time, but at 2,080 hours a year it is 4.8 years of full-time work. At 20 hours a week, it takes about 9.6 years.
