A big data study conducted by KB Kookmin Card Co. revealed that card expenditures on lobster, crab and duck meat spiked on Children’s Day throughout the entire month of May between 2018 and 2021.
From May 5 to 7, 2018, and May 4 to 6, 2019, daily card spending at restaurants was 14 to 52 percent more than the month's daily average.
Daily card expenditures at restaurants on May 5, 8, and 9 in 2020 were 9 to 22 percent higher than the month's daily average, significantly lower than the previous year when COVID-19 social distancing measures were in effect.
Daily spending on May 5 and 8 last year was no more than 22 percent and 49 percent greater than the month's daily average, respectively. Despite the fact that it was the Sunday after Parent's Day, daily expenditure increased by only 9 percent on May 9.
