How many seconds are there in one light-year?

31,536,000 seconds because 365 days a year, 24 hours a day. Every hour is 60 minutes, and each minutes 60 seconds. So to get the answer 60 sec/min x 60 min/hr x 24 hr/day x 365 days/year = 31,536,000 seconds.

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year
