Errors and Exceptions

• Code #1: If in Date() constructor we do not give any year, still setUTCFullYear() function will be able to set new year according to universal time which is given as its parameter.

  // Here year according to universal time has not // been assigned while creating Date object var dateobj = new Date('October 13, 05:35:32 GMT-3:00');    // new year 1992 is being set in above Date // Object with the help of setUTCFullYear() function dateobj.setUTCFullYear(1992);    // new year from above Date Object is // being extracted using getUTCFullYear() var B = dateobj.getUTCFullYear();    // Printing new year console.log(B);

  Output:

  > 1992

• Code #2: If nothing as parameter is given in Date() constructor, still setUTCFullYear() function will be able to set year in the created Date object but month and date remains current ones.

  // Here nothing has been assigned // while creating Date object var dateobj = new Date();    // new year 2007 is being set in above Date // Object with the help of setUTCFullYear() function dateobj.setUTCFullYear(2007);    // Year from above Date Object is // being extracted using getUTCFullYear() var B = dateobj.getUTCFullYear();    // month from above Date Object is // being extracted using getUTCMonth() var C = dateobj.getUTCMonth();    // date from above Date Object is // being extracted using getUTCDate() var D = dateobj.getUTCDate();    // Printing new year console.log(B);    // Printing current month console.log(C);    // Printing current date console.log(D);

  Output:

  > 2007
  > 2
  > 30

  Here in output 2 is the month of March because month name start from 0 to 11 i.e, 0 for January and 11 for December.
  And 30 is the current date.
