DateOnly is a data type that will only store a date, without an associated time. This allows you to work with dates without having to worry about time zones shifting the date.
A simple example is a person's birthday - a birthday is not a single moment in time, but rather a full day. DateOnly is the perfect data type to represent such data.
npm install dateonly// CommonJS
var DateOnly = require('dateonly');// AMD
require(['DateOnly'], function(DateOnly) { ... });// Script Tag
var DateOnly = window.DateOnly;var DateOnly = require('dateonly');
var myBirthday = new DateOnly('7/4/1980');new DateOnly(defaultValue)defaultValue: undefined
If nothing is passed into the DateOnly constructor, it will default to today's date.
defaultValue: Date
If a Date object is passed in, the DateOnly instance will be set to the Date's date.
defaultValue: String
If a String is passed in, it will be passed to the Date constructor, and that new Date instance will then be used to set the DateOnly's date.
defaultValue: Number
If a Number is passed in, it will be passed to the Date constructor, and that new Date instance will then be used to set the DateOnly's date.
new DateOnly().setDate(date)Sets the date portion of the DateOnly instance.
date: Number
The number to set the date to. No validation is performed.
Example:
var date = new DateOnly('1/1/2000');
date.setDate(20);
console.log(date); // { date: 20, month: 0, year: 2000 }
date.setDate(80);
console.log(date); // { date: 80, month: 0, year: 2000 }new DateOnly().getDate()Gets the date portion of the DateOnly instance.
new DateOnly().setMonth(month)Sets the month portion of the DateOnly instance. As with the Date object, January === 0.
month: Number
The number to set the month to. No validation is performed.
new DateOnly().getMonth()Gets the year portion of the DateOnly instance.
new DateOnly().setFullYear(year)Sets the year portion of the DateOnly instance.
month: Number
The number to set the year to. No validation is performed.
new DateOnly().getFullYear()Gets the year portion of the DateOnly instance.
new DateOnly().getDay()Gets the day of the week of the DateOnly instance. As with the Date object, Sunday === 0.
new DateOnly().toDate()Returns the Date representation of the DateOnly instance.
Example:
var dateOnly = new DateOnly('1/1/2000');
dateOnly.toDate() instanceof Date // true
dateOnly.toDate(); // Sat Jan 01 2000 00:00:00 GMT-0600 (CST)new DateOnly().valueOf() | new DateOnly().toJSON()Returns the numeric representation of the DateOnly instance, of the form YYYYMMDD.
Example:
var dateOnly = new DateOnly('7/15/2000');
dateOnly.valueOf() // 20000615
dateOnly.toJSON() // 20000615new DateOnly().toString()Returns the date string of the DateOnly instance. This is equivalent to calling new DateOnly().toDate().toDateString().
Example:
var dateOnly = new DateOnly('7/4/2000');
dateOnly.toString() // 'Tue Jul 04 2000'If you are using Mongo and Mongoose, there is a package that will allow you to store and query DateOnly properties that can be found here.
