Worried about when you can find? Facebook knows. This is according to a table in the online series that uses Facebook to track updates this time of year, people are separating.

British journalist and graphic designer David McCandless, who specializes in showcasing data in visual ways, compiled the chart. He showed off the graphic at a TED conference last July in Oxford, England.

In the talk, McCandless said he and a colleague scraped 10,000 Facebook status updates for the phrases “breakup” and “broken up.”

They found two big spikes on the calendar for breakups. The first was after Valentine’s Day — that holiday has a way of defining relationships, for better or worse — and in the weeks leading up to spring break. Maybe spring fever makes people restless, or maybe college students just don’t want to be tied down when they’re partying in Cancun.

And let’s hear it for cheapskates. The other big romantically treacherous time, according to the graph, is about two weeks before Christmas — presumably as people begin pricing gifts for their significant others.

Monday, as if it were not bad enough, is the day most likely be separated. summer and autumn look like the safest seasons.

And, perhaps to show that people feel part of the humor is more twisted than others, there is a peak in case of failure on the Day of the Innocents. One day you’re less likely to get a Dear John (or Jane) letter?

“Christmas Day,” McCandless said. “Who would do that?”
