js date and time code example
Example 1: javascript get time
// these are the most useful ones IMO
var time = new Date();
time.getDate(); // returns value 1-31 for day of the month
time.getDay(); //returns value 0-6 for day of the week
time.getFullYear(); //returns a 4 digit value for the current year
time.getHours(); //returns value 0-23 for the current hour
time.getMinutes(); //returns value 0-59 for the current minute of the hour
time.getSeconds(); //returns value 0-59 for current second of the minute
time.getMilliseconds(); //returns value 0-999 for current ms of the second
time.getTime(); //returns date as ms since Jan 1, 1970
time.toDateString(); //returns a string (e.g. "Fri May 9 2020")
time.toLocaleString(); //returns date and time (e.g. "9/12/2015, 6:08:25 PM")
time.toLocaleTimeString(); //returns time (e.g. "6:08:25 PM")
time.toLocaleDateString(); //returns date (e.g. "9/12/2015")
Example 2: how to use current data in javascript
var today = new Date();
var date = today.getFullYear()+'-'+(today.getMonth()+1)+'-'+today.getDate();
Example 3: js date methods
var d= new Date();
d.getFullYear(); //Get the year as a four digit number (yyyy)
d.getMonth(); //Get the month as a number (0-11)
d.getDate(); //Get the day as a number (1-31)
d.getHours(); //Get the hour (0-23)
d.getMinutes(); //Get the minute (0-59)
d.getSeconds(); //Get the second (0-59)
d.getMilliseconds() //Get the millisecond (0-999)
d.getTime(); //Get the time (milliseconds since January 1, 1970)
d.getDay(); //Get the weekday as a number (0-6)
d.Date.now(); //Get the time. ECMAScript 5.
d.setDate() //Set the day as a number (1-31)
d.setFullYear() //Set the year (optionally month and day)
d.setHours() //Set the hour (0-23)
d.setMilliseconds() //Set the milliseconds (0-999)
d.setMinutes() //Set the minutes (0-59)
d.setMonth() //Set the month (0-11)
d.setSeconds() //Set the seconds (0-59)
d.setTime() //Set the time (milliseconds since January 1, 1970)
Example 4: javascript date methods
var d= new Date();
d.getFullYear();//Get the year as a four digit number (yyyy)
d.getMonth();//Get the month as a number (0-11)
d.getDate();//Get the day as a number (1-31)
d.getHours();//Get the hour (0-23)
d.getMinutes();//Get the minute (0-59)
d.getSeconds();//Get the second (0-59)
d.getMilliseconds();//Get the millisecond (0-999)
d.getTime();//Get the time (milliseconds since January 1, 1970)
Example 5: javascript date
var d= new Date();
d.getFullYear();//Get the year as a four digit number (yyyy)
d.getMonth();//Get the month as a number (0-11)
d.getDate();//Get the day as a number (1-31)
d.getHours();//Get the hour (0-23)
d.getMinutes();//Get the minute (0-59)
d.getSeconds();//Get the second (0-59)
d.getMilliseconds();//Get the millisecond (0-999)
d.getTime();//Get the time (milliseconds since January 1, 1970)
Example 6: javascript date
var currentDate = new Date();
var dateFromTimeStamp= new Date(1560807962);
var dateFromString = new Date('December 17, 1995 03:24:00');
//new Date(year, month, day, hours, minutes, seconds, milliseconds)
//0= Jan, 11=Dec
var dateFromYearMonthDay = new Date(2018, 11, 26, 0, 0, 0, 0);
