Parse natural language
For event dates and times, it would be nice to let the user type free-form with strings like:
- Next monday
Both in the user's native language and in English (some people to type strings directly in English).
As well as various number formats as seen on http://xkcd.com/1179/
Time could accept formats such as:
- 10pm, 10 PM, 10h PM, ... (if you want to go nuts)
We could even go further and autodetect date/time keywords like that inside event descriptions that are typed in the simplified "New event" dialog.
