I am 28 years old and I left the church 5 months ago around my 28th bday. Lets estimate how much time I wasted on church. Will start from 8 because that is when became an official member and I think church was still kind of fun until I hit 8.

Note: other church things means scripture study, prayer, fasting, hometeaching, callings, temple trips, and whatever else. The ages are up to the end of the year I put. For example 8-11 includes the year 11.

8-11 - 3 hours of church a week, other church things 1 hour a week. hours=4*4*52 = 832

12-14 - 3 hours of church, 4 hours of other things.
hours=3*7*52 = 1,092

15-18 - 3 hours of church, 5 hours of seminary, 4 hours of other things.
hours=4*12*52 = 2,496

Mission 2 years = 17,520

21-27 - 3 hours of church, 7 hours of other things.
hours=7*10*52 = 3640

Total hours 832+1092+2496+17520+3640 = 25,580 hrs

or 1066 days or 2.92 years.

How much time did you spend on church?

4 years you forgot to factor in the Temple trips, sure it's not a factor in the corridor where there's one on every corner. But say for an Edmontonian Mormon, he has to drive ALL the way south. It's 3 hours to Calgary, then an additional 3 hours to Cardston, so 6 hours for a round trip. or 12 hours.

For a Vancouverite Mormon there is no temple save Bellevue, for some Mormons over seas, there is just one temple per country!

Enough to realize that I wasted 19 years of my life.

Primary, 1963-72 = 520 hours
Mutual, 1975-78 = 208 hours
Sunday mtgs, 1975-79 = 520 hours
Seminary, 1976-78 = 540 hours

Total = 1788 hours or 74.5 days

That's probably a generous estimate.

How 'bout including amount of time we spend on this website?
