# For each holiday and each restaurant open that day: covers that day ÷ the restaurant’s average covers on the same weekday 2, 3 and 4 weeks before and after (holiday weeks excluded by construction). Median over restaurants; 100 = a normal day of that weekday. Only restaurants with reservations that day count, so closures do not drag the index down.
