On Monday, the day after Mother's Day, 10 times more women opened an account at Ashley Madison than do on a normal Monday.

This Monday, 31,427 women took the first step toward an extramarital affair by setting up a profile on Ashley Madison, a dating site for married people. The day after Mother's Day is always Ashley Madison's second-busiest of the year. It's sandwiched between the day after Valentine's Day and the day after New Year's.

According to Noel Biderman, the president of Ashley Madison, days after holidays are big for female sign-ups "because [women] have expectations -- expectations that their partnership will be celebrated and even romanticized -- but that is often not what transpires."
