Answer 1

To start your node in PST time zone , use following command in ubuntu.

TZ=\"/usr/share/zoneinfo/GMT+0\" && export TZ && npm start &

Then You can refer Date Library to get the custom calculation date and time functions in node.

To use it client side refer this link, download index.js and assertHelper.js and include that in your HTML.

$( document ).ready(function() {
    DateLibrary.getDayOfWeek(new Date("2015-06-15"),{operationType:"Day_of_Week"}); // Output : Monday
}

You can use different functions as given in examples to get custom dates.

If first day of week is Sunday, what day will be on 15th June 2015.

 DateLibrary.getDayOfWeek(new Date("2015-06-15"),
    {operationType:"Day_Number_of_Week",
        startDayOfWeek:"Sunday"}) // Output : 1

If first day of week is Tuesday, what week number in year will be follow in 15th June 2015 as one of the date.

 DateLibrary.getWeekNumber(new Date("2015-06-15"),
    {operationType:"Week_of_Year",
        startDayOfWeek:"Tuesday"}) // Output : 24

Refer other functions to fulfill your custom date requirements.
