You've come to the right place. OhMyGov has the best Federal Pay Calendar for 2012 so far.  If you want to know when that money will appear in your bank account, or if you are looking for more information, including all those federal holidays, pay periods and your payroll dates, you have a choice between the following detailed pay calendars: either Justice's federal pay calendar for 2012, GSA's federal pay calendar for 2012 or the 2012 Fiscal Pay Calendar.

OhMyGov! gives special kudos to the folks at the US Department of Justice and the General Services Administration.
