Dating has been mostly about the chemistry between two people; for years, people made decisions based on the initial burst of spark. The effortless, intense conversations during the first few weeks, the butterflies, and the peak attraction, all played an important role in commitment. 

But then came a sudden, quiet shift; Indian singles started looking beyond the colourful first weeks; they wanted a peek at the days when the butterflies fled and were replaced by the mundane moth, said respondents in a recent survey by Indian dating app, QuackQuack. The app studied the responses of 9,911 Indian singles who are actively dating about the currently popular trend of Compatibility Window to understand how and why the dating pattern started gaining traction.
