But those days just involve an hour or a little more at mass. One can still go to work or school on a holy day of obligation or a football game on Sunday without any problem, as long as the obligation attend mass is fulfilled.

The Jewish High Holy Days are full-day observances that require fasting and avoiding all activity except religious observances. No school. No work. No recreational activities. And it's pretty well understood that many Jews who are not particulaly observant about Sabbath-keeping are very observant when it comes to the High Holy Days.

Exactly. These days (or Christmas) are the apt comparisons to the High Holy Days. Sundays and holy days of obligation are comparable to the Sabbath, about which see above.
