Dating Sunday, also known as "Singles Sunday," is the busiest day of the year for online dating. On this day, dating apps and websites see a massive surge in activity as singles flock to find love and connection.

Dating Sunday is the first Sunday after the New Year. It earned its name because it happens to be the day in which those who broke up in December before the holidays, those who were uber holiday focused, and those who set New Year's Resolutions centered around finding love take the plunge and download an online dating app.
