![]() ![]() Month: April (because month is zero-indexed) This date can be easily read if you follow the left-right formula. As you go left to right, you insert values in decreasing magnitude: year, month, day, hours, minutes, seconds, and milliseconds. Many developers (myself included) avoid the the arguments approach because it looks complicated. You can pass in up to seven arguments to create a date/time. If you want to create dates, use arguments or timestamps. MDN recommends against creating date with date strings. (By the way, MDN warns against the date-string approach since browsers may parse date strings differently). So, I recommend you don’t create dates with date strings. UTC thing with date-strings can be a possible source of error that’s hard to catch. new Date('T00:00') Date created in Local Time vsl. When you include time, you need to write the HH and mm at a minimum (or Google Chrome returns an invalid date). If you want to create a date in Local Time with the date-string method, you need to include the time. This is why people who live in areas behind GMT get a 10th June instead of 11th June. In the above scenario, when you write new Date(''), you actually create a date that says 11th June, 2019, 12am UTC. This happens because the date-string method has a peculiar behavior: If you create a date (without specifying time), you get a date set in UTC. new Date('') produces 11th June if you’re in a place after GMT. If you live in an area that’s ahead of GMT, you’ll get a date that says 11th June. new Date('') produces 10th June if you’re in a place behind GMT. ![]() If you live in an area that’s behind GMT, you’ll get a date that says 10th June. ![]() You can spot the problem if you console.log this date. There’s a huge problem with creating dates with date strings. So, if you want to create a date for 11th June 2019, you can write this: new Date('') Hours, minutes, seconds and milliseconds are optional if you’re creating a date. If Z is not present, it’ll be Local Time.
