Use this workflow to get the difference between two dates in Alfred. This relies exclusively on PHP 5.3+'s [DateInterval](http://www.php.net/manual/en/dateinterval.format.php) method, which is happy to accept a variety of inputs and works pretty well! Examples:
2+
3+
- `datespan tomorrow`: countdown in hours and minutes
4+
- `datespan 10/10/10`: difference in years, months, days, hours, and minutes—along with total business weeks, weeks, days, hours, and minutes
5+
- `datespan 3/10 to 5/12`: all units above, but the span between zero-hour on each date
6+
7+
You can use any format that [`strtotime`](https://php.net/manual/en/function.strtotime.php) can parse, so I'm sure there are plenty of variations I've not thought to try yet.
8+
9+
Screenshots with a few more examples [on my humble blog](http://workingconcept.com/blog/date-span-alfred-workflow).

Comments, suggestions, criticisms, and pull requests all welcome!

<string>Add a single date to see the difference in years, months, business weeks, weeks, days, hours, and minutes from today.
77+
78+
Add two dates to see the difference between the two, in the same units as above.
79+
80+
This will use any string that PHP can convert into a date, so all the following are valid input…
81+
82+
- “1/1/13”
83+
- “1/1/13 to 10/31/13”
84+
- “january 1”
85+
- “january 1 to march 31”
86+
- “8:15pm”
87+
- “9am to 5pm”
88+
89+
Please improve this plugin if you’d like, or just say hi—I’d love to know if you’ve found it useful!
