But there’s another story in the numbers, too, particularly when you look at changes in how fathers spend their time since 1965. Back then, a father’s “second shift” — his combined housework and childcare time — was a grand total of 6.5 hours per week. These days, it’s up to 17 hours. In other words, dads have almost tripled their household workload over the last 50 years. And the most fascinating part is that many dads still don’t feel like they’re doing enough. While the Pew survey found that only 23 percent of moms say they spend too little time with their kids, 46 percent of men think that. While 73 percent of moms say they are doing an excellent or very good job at parenting, only 64 percent of fathers say the same.

In other words, there’s been a sea change in how men think a good father spends his time. While men in the past thought their duty was to support their kids financially — full stop — modern men feel differently. They show this both in how they spend their hours, and their expectations of themselves.
