We suffered through a long Grey's Anatomy Season 10 winter hiatus, but our reward is 12 uninterrupted weeks of Greys goodness. So, when does that make the finale? Well, a little handy math tells us Grey's will end on May 15, 2014, and a new press release from ABC confirms that is the finale date.

While the writers haven't said much about how this season will end, we can expect this episode to be a big deal. First of all, it's a Grey's finale, which are always crazy. Second, it marks the end of Grey's first decade on TV, which is a pretty huge deal. And, most importantly, it's Sandra Oh's (Cristina Yang) last episode as a series regular. We expect Cristina to get a goodbye worthy of one of the most kick-butt women to ever grace our TV screens.

We expect we'll need an entire box of tissues to make it through Cristina's departure (no more Twisted Sisters? We can't even think about it), but the good news is that at least we know Ellen Pompeo (Meredith Grey) and Patrick Dempsey (Derek Shepherd) are back for two more years, and we have a feeling the rest of the original cast will also return.

So mark your calendars for May 15, 2014, when the finale will air at its usual 9 p.m. ET timeslot on ABC.
