No better time to browse for new apps than when your exams are round the corner. :/
Here's a bunch of calendar apps:
Simple Calendar -- As the name implies, it's, well, simple. Just shows a monthly view like the default calendar app, but you can see the event names on the calendar grid itself, and event details below that. Also has a very Metro-looking (i.e. beautiful) live tile which shows multiple events.
Calendar[+] -- Has a bunch of different views, live tile isn't so nice though. And unless I'm missing something it doesn't have double-wide tiles, but I suppose it'll probably be updated eventually.
Chronos Calendar -- Tons of customization options, especially for the live tile. You can put a background picture, change the colour and transparency of the border and text, set what to show/not to show etc.
Was also playing around with
Perfect365, it's a makeup app. Works kinda like face customization in games like Saints Row, The Sims etc. Pretty fun, but probably not of much use to (single) guys. :/
