I don't know when this got put into iOS, but I think it's brilliant.
Go onto Notes, either add a new note or just use the current one. Then type something such as:
iOS recognises anything like those bits of text as a time and date. You just select the underlined text and it pops up with a "Create Event" option, and it adds it to the calendar!
I don't know how well known this feature is but I find it so much quicker to quickly enter a date and time into Notes and get iOS to do all the work for me. Haven't tried it but it might even work in emails.

Oops, how do I make the picture smaller? =/
