Day From 1970

A node.js module of calculating out witch day, month, year and week from 1970.1.1 via one timestamp.

Application Scenario

When you want to GROUP data by Week, Day, Month and Year, maybe you need it.

This module allows you to pass an integer of timestamp as a parameter, and it will calculate out which day is this timestamp from 1970/01/01, which week is this timestamp from 1970/01/01, which month and even witch year.

Installation

$ npm install day-from-1970 --save

or

$ bower install day-from-1970 --save

Usage

df1970(timestamp, [timezone], [firstday]);

Timestamp above is the timestamp of one second.

The second parameter timezone is optional, which stands for the timezone (from -12 to 12). if no timezone is specified, the default value is your current timezone.

And the third parameter is opitional, which stands for the first day of one week.

1 stands for Monday and 7 stands for Sunday. And you can pass 1 ~ 7 as the second parameter.

And it will return an object like:

{
  "day": 16169,
  "week": 2311,
  "month": 532,
  "year": 45
}

So the test code is below:

var df1970 = require("day-from-1970");
var t = 1396946977;
var list = [];
for(var i = 0; i < 10; i++) {
    list.push(df1970(t));
    t += 86400;
}

console.log(list);
