It identifies the difference between AM and PM. when someone enters a time it will calculate the time in 24 hours format and then it will convert it in 12 hr format. As a result, the user can see the result as 12 hours format and based on that it will change the timestamp in am or pmtechnical analysis :date.slice(-2); // this code is used for cut the last 2 words from the time, which is AM or PM. So, it can be used for latervar stHour // For hours calculationvar stMin // For minutes calculationvar stAmPm // For AM or PM calculation
