How to get 2 digit year w/ Javascript? [duplicate]

Question

I am trying to find some javascript code that will write the current date in this format: mmddyy

Everything I have found uses 4 digit years and I need 2 digit.

Answer 1

The specific answer to this question is found in this one line below:

//pull the last two digits of the year //logs to console //creates a new date object (has the current date and time by default) //gets the full year from the date object (currently 2017) //converts the variable to a string //gets the substring backwards by 2 characters (last two characters)     console.log(new Date().getFullYear().toString().substr(-2));

Formatting Full Date Time Example, Single Function (MMddyy): jsFiddle

JavaScript:

//A function for formatting a date to MMddyy function formatDate(d) {     //get the month     var month = d.getMonth();     //get the day     //convert day to string     var day = d.getDate().toString();     //get the year     var year = d.getFullYear();          //pull the last two digits of the year     year = year.toString().substr(-2);          //increment month by 1 since it is 0 indexed     //converts month to a string     month = (month + 1).toString();      //if month is 1-9 pad right with a 0 for two digits     if (month.length === 1)     {         month = "0" + month;     }      //if day is between 1-9 pad right with a 0 for two digits     if (day.length === 1)     {         day = "0" + day;     }      //return the string "MMddyy"     return month + day + year; }  var d = new Date(); console.log(formatDate(d));

Formatting Full Date Example, multiple functions (MMddyy):

// function getMonth with 1 parameter expecting date // This function returns a string of type MM (example: 05 = May) function getMonth(d) {     //get the month     var month = d.getMonth();          //increment month by 1 since it is 0 indexed     //converts month to a string     month = (month + 1).toString();      //if month is 1-9 pad right with a 0 for two digits     if (month.length === 1)     {         month = "0" + month;     }          return month; }  // function getDay with 1 parameter expecting date // This function returns a string of type dd (example: 09 = The 9th day of the month) function getDay(d) {     //get the day     //convert day to string     var day = d.getDate().toString();            //if day is between 1-9 pad right with a 0 for two digits     if (day.length === 1)     {         day = "0" + day;     }          return day; }  // function getYear with 1 parameter expecting date // This function returns the year in format yy (example: 21 = 2021) function getYear(d) {     //get the year     var year = d.getFullYear();          //pull the last two digits of the year     year = year.toString().substr(-2);          return year; }  //A function for formatting a date to MMddyy function formatDate(d) {     //return the string "MMddyy"     return getMonth(d) + getDay(d) + getYear(d); }  var d = new Date(); console.log(formatDate(d));

Answer 2

Given a date object:

date.getFullYear().toString().substr(2,2); 

It returns the number as string. If you want it as integer just wrap it inside the parseInt() function:

var twoDigitsYear = parseInt(date.getFullYear().toString().substr(2,2), 10); 

Example with the current year in one line:

var twoDigitsCurrentYear = parseInt(new Date().getFullYear().toString().substr(2,2));
