Doing Date Math on the Command Line, Parts I & II | Linux Journal
If you’ve ever used a spreadsheet, you’ve probably used or seen functions for doing date math—in other words, taking one date and adding some number of days or months to it to get a new date, or taking two dates and finding the number days between them. The same thing can be done from the command line using the lowly date command, possibly with a little help from Bash’s arithmetic.

Link: Our Favourite Linux Cheat Sheets
Most Linux system administrators spend their days at the command line, configuring and monitoring their servers through an SSH session. The command line is extremely powerful, but it can be difficult to keep all the options switches and tools in your head. Man pages are only a command away, but they’re often not written for quick consultation, so when we’re stuck for some of the more arcane options, we reach for the collection of cheat sheets that we’ve curated over the years.
Even command line masters occasionally need a litte help, and we hope that terminal beginners will find these concise lists useful too. All of these tools are installed by default on a standard Linux box except for Vim and Emacs, which may or may not be available (see the package manager cheat sheets for how to get them).
