Date object (JS built-in object)

Basic usage ：

<script>        
        // Current time object ( Automatically get the current time of the server )

        var date = new Date()

        console.log(date)


        //UTC 1970.1.1 00:00:00(Date In the object , Save from 1970 year 1 month 1 Japan 00:00:00 The number of milliseconds up to now )

        var date1 = new Date(0)

        console.log(date1)


        //UTC 1970.1.1 00:00:01((1 second =1000 millisecond ))

        var date3 = new Date(1000)

        console.log(date3)


        // Custom time 

        var date2 = new Date("2022/4/1 12:00:00")

        console.log(date2)


        // Returns the number of milliseconds (1 second =1000 millisecond )

        // obtain 1970 year 01 month 1 Japan 0 The number of milliseconds since zero 

        console.log(date2.getTime())


        // Calculation 5 Minutes later 

        var date3 = new Date()

        // Transformation format (Sat Apr 02 2022 11:26:21 GMT+0800 ( China standard time ))

        console.log("5 Minutes later, the time is :" + new Date(date3.getTime() + 5 * 60 * 1000))


        // Subtract two times ( Get timestamp ) Returns the number of milliseconds 

        console.log(date3 - date2)


        // Get year 

        console.log(date.getFullYear() + " year ")


        // Get month ( Month from 0 Start )

        console.log(date.getMonth() + 1 + " month ")


        // Acquisition date 

        console.log(date.getDate() + " Japan ")


        // Get week 

        console.log(" week " + date.getDay())


        // For hours 

        console.log(date.getHours() + " when ")


        // Get minutes 

        console.log(date.getMinutes() + " branch ")


        // Get seconds 

        console.log(date.getSeconds() + " second ")


        // Get local date 

        console.log(date.toLocaleDateString())


        // Get local time 

        console.log(date.toLocaleTimeString())


        // Get local date and time 

        console.log(date.toLocaleString())
</script>

It is worth noting that the month is from 0 The beginning of the calculation , Don't forget the real month +1！！
