Yom Kippur, the day of atonement, starts tonight at sundown. And suffice to say, it's a bit more serious than Rosh Hashanah—so there are no Muppets-related videos to get your toes tapping tonight. Instead, there are very serious subway and train difficulties awaiting you this weekend, as you contemplate all the wrongs you have perpetrated this year.

There will be no L train running this weekend—and there are (as usual) a ton of other headache-inducing changes, all of which you can handily find in one place here. But, there were nine extra eastbound Long Island Rail Road trains in service to help shuttle people from Penn Station to some more prayer-appropriate settings.

So plan accordingly with all the changes, mind your manners, let any last minute Russ And Daughters dreams fall by the wayside...and whatever you do, don't forget to take your sacred caffeine suppository.
