It’s quite common for employment lawyers to be interested about the day of the week a particular date fell on in the past. For example, it might be important that an email was sent on a Friday, inviting someone to a meeting on a Monday — rather than having been sent on a Monday, for a Wednesday meeting.
Computers have made this considerably easier. Most electronic diaries will allow you to go back in time far further than is ever likely to be necessary.
But this does often require quite a bit of clicking, especially to go back a few years. If you work on a Mac (or otherwise have access to a Unix command line) I’ve found a better, if slightly geeky way.
Just open a terminal window and type ‘cal 11 2013’. You’ll instantly get a small calendar of the 11th month in 2013, including days of the week. If you need January 2011, type ‘cal 1 2011’.
