How to check if two dates not on the same calendar day

Another option is using .toDateString() function to parse both dates into strings. The function formats output to: “Wed Jul 28 1993.” Then you can compare both date strings.

actualDate.toDateString() === dateToCheck.toDateString()
// returns true if actualDate is same day as dateToCheck
