I just noticed the NYSE is closed today for the President's Day (Washington's Birthday) holiday.
Is there a comprehensive list of all dates the NYSE would be typically closed for? Would the dates be the same for other U.S. exchanges like NASDAQ and AMEX and the options exchange?
The NYSE publishes a list of holidays at its website.

Hope that helps!
Stumbled upon this question, I've found the updated dates for 2016 and 2017 in a more permanent location.
All public US equity exchanges are closed on the 9 US trading holidays (see below) and open on all other days. Exchanges also close early (13:00 ET) on the Friday after Thanksgiving and on the day before Independence Day if Independence Day is being observed on a Tuesday, Wednesday, Thursday, or Friday. (Some venues have extended trading hours as a matter of course; for them an "early close" might be later than 13:00 ET.)
To answer the second question, yes, if you know NASDAQ's or AMEX's holiday schedule, then you know NYSE's (modulo the timing of their early close). I'm not sure about the options exchanges; they're not regulated the same way and are a good example of exchanges with extended trading hours in the first place.
The US trading holidays are as follows. Note that trading holidays are not the same as federal or bank holidays, which include Columbus Day and Veterans Day but do not include Good Friday.
