Location-specific effects of time of festival on positive affect, showing lower positive affect in the less traditional context (Delhi, left panel) compared to a more traditional context (Prayagraj, right panel). Note: curvilinear effect in Prayagraj is not statistically reliable. Time is coded as −2 (one week before festival), −1 (2 days before the main festival day), 0 (main day of Diwali), 1 (2 days after the main day), 2 (one week after). (Online version in colour.)
