Problem: That is because your day is 29 today and in February, max date is 28. when you try to set month as 1 (Feb) and date as 29 which is already set. It automatically increases the month ;)

For example:

 var overMaxDate = new Date('2018-03-29'); overMaxDate.setMonth(1) console.log(overMaxDate.toLocaleDateString()); var maxDate = new Date('2018-03-28'); maxDate.setMonth(1) console.log(maxDate.toLocaleDateString()); 

Solution: You can use https://momentjs.com/ library to manipulate date any way you like. Or you can also keep track of days. Good luck!
