Persian Date

Javascript date library for parsing, validating, manipulating, and formatting persian dates System.

Inspired by momentjs

Install

npm install persian-date
bower install persian-date

Browser

<script src="pwt-date.js"></script>
<script>
    persianDate().format();
</script>

Parse

Instead of modifying the native Date.prototype , persianDate.js creates a wrapper for the Date object. To get this wrapper object, simply call persianDate() with one of the supported input types.

Now

persianDate();

To get the current date and time, just call persianDate() with no parameters.

var now = persianDate();

This is essentially the same as calling persianDate(new Date()) .

Unix Offset (milliseconds)

persianDate(Number);

Similar to new Date(Number), you can create a persianDate by passing an integer value representing the number of milliseconds since the Unix Epoch (Jan 1 1970 12AM UTC).

var day = persianDate(1318781876406);//"۱۳۹۰-۰۷-۲۴ ۱۹:۴۷:۵۶ ب ظ"

Unix Timestamp (seconds)

persianDate.unix(Number)

To create a persianDate from a Unix timestamp (seconds since the Unix Epoch), use persianDate.unix(Number)

var day = persianDate.unix(1318781876);//"۱۳۹۰-۰۷-۲۴ ۱۹:۴۷:۵۶ ب ظ"

This is implemented as persianDate(timestamp * 1000) , so partial seconds in the input timestamp are included.

var day = persianDate.unix(1318781876.721);

Date

persianDate(new Date());

You can create a persianDate with a pre-existing native Javascript Date object.

var day = new Date(2011, 9, 16);
var dayWrapper = persianDate(day);//"۱۳۹۰-۰۷-۲۴ ۰۰:۰۰:۰۰ ق ظ"

This is the fastest way to get a persianDate.js wrapper.

Array

persianDate([Number...]);

You can create a persianDate with an array of numbers that mirror the parameters passed to new Date() But As Persian Date Number Like [1393,2,22,11,22,30]

Note:In this version array of Gregorian Date dose not Support

[year, month, day, hour, minute, second, millisecond]
persianDate([1393, 1, 14, 15,25, 50,125]); // "۱۳۹۳-۰۱-۱۴ ۱۵:۲۵:۵۰ ب ظ"

Any value past the year is optional, and will default to the lowest possible number.

persianDate([1392]); // Farvardin 1st
persianDate([1392, 6]); // Shahrivar 1st
persianDate([1392, 6, 10]); // Shahrivar 10th

PesianDate Clone

persianDate(persianDate);

All persianDate are mutable. If you want a clone of a persianDate, you can do so explicitly or implicitly. Calling persianDate() on a persianDate will clone it.

var a = persianDate([1392]);
var b = persianDate(a);
a.year(1300);
b.year(); // 1392

var a = persianDate([1392]);
var b = a.clone();
a.year(1300);
b.year(); // 1392

ASP.NET JSON Date

persianDate(String);

ASP.NET returns dates in JSON as /Date(1198908717056)/ or /Date(1198908717056-0700)/

If a string that matches this format is passed in, it will be parsed correctly.

persianDate("/Date(1198908717056-0700)/"); //"۱۳۸۶-۱۰-۰۸ ۰۹:۴۱:۵۷ ق ظ"

Get + Set

persainDate.js uses overloaded getters and setters. You may be familiar with this pattern from it's use in jQuery.

Calling these methods without parameters acts as a getter, and calling them with a parameter acts as a setter.

These map to the corresponding function on the native Date object.

persianDate().seconds(30) === new Date().setSeconds(30);
persianDate().seconds()   === new Date().getSeconds();

Millisecond

persianDate().millisecond(Number);
persianDate().millisecond(); // Number
persianDate().milliseconds(Number);
persianDate().milliseconds(); // Number

Gets or sets the milliseconds.

Accepts numbers from 0 to 999. If the range is exceeded, it will bubble up to the seconds.

Second

persianDate().second(Number);
persianDate().second(); // Number
persianDate().seconds(Number);
persianDate().seconds(); // Number

Gets or sets the seconds.

Accepts numbers from 0 to 59. If the range is exceeded, it will bubble up to the minutes.

Minute

persianDate().minute(Number);
persianDate().minute(); // Number
persianDate().minutes(Number);
persianDate().minutes(); // Number

Gets or sets the minutes.

Accepts numbers from 0 to 59. If the range is exceeded, it will bubble up to the hours.

Hour

persianDate().hour(Number);
persianDate().hour(); // Number
persianDate().hours(Number);
persianDate().hours(); // Number

Gets or sets the hour.

Accepts numbers from 0 to 23. If the range is exceeded, it will bubble up to the day.

Date of Month

persianDate().date(Number);
persianDate().date(); // Number
persianDate().dates(Number);
persianDate().dates(); // Number

Gets or sets the day of the month.

Accepts numbers from 1 to 31. If the range is exceeded, it will bubble up to the months.

Note: persianDate#date is for the date of the month, and persianDate#day is for the day of the week.

Year

persianDate().year(Number);
persianDate().year(); // Number
persianDate().years(Number);
persianDate().years(); // Number

Gets or sets the year.

Accepts numbers from -270,000 to 270,000.

Day of Week

persianDate().day(); // Number
persianDate().days(); // Number

Gets the day of the week.

Note: persianDate#date is for the date of the month, and persianDate#day is for the day of the week.

Manipulate

Once you have a PersianDate , you may want to manipulate it in some way. There are a number of methods to help with this.

persianDate.js uses the fluent interface pattern, also known as method chaining. This allows you to do crazy things like the following.

persianDate().add('days', 7).subtract('months', 1).year(2009).hours(0).minutes(0).seconds(0);

Note: It should be noted that persianDates are mutable. Calling any of the manipulation methods will change the original persianDate.

If you want to create a copy and manipulate it, you should use persianDate#clone before manipulating the persianDate.

Add

persianDate().add(String, Number);

Mutates the original persianDate by adding time.

This is a pretty robust function for adding time to an existing persianDate. To add time, pass the key of what time you want to add, and the amount you want to add.

persianDate().add('days', 7);

There are some shorthand keys as well if you're into that whole brevity thing.

persianDate().add('d', 7);

Key	Alternate	Shorthand
years	year	y
months	month	M
weeks	week	w
days	day	d
hours	hour	h
minutes	minute	m
seconds	second	s
milliseconds	millisecond	ms

If you want to add multiple different keys at the same time, you can pass them in as an object literal.

persianDate().add('days', 7).add('months', 1); // with chaining

There are no upper limits for the amounts, so you can overload any of the parameters.

persianDate().add('milliseconds', 1000000); // a million milliseconds
persianDate().add('days', 360); // 360 days

Subtract

persianDate().subtract(String, Number);

Mutates the original persianDate by subtracting time.

This is exactly the same as persianDate#add , only instead of adding time, it subtracts time.

persianDate().subtract('days', 7);

Start of Time

persianDate().startOf(String);

Mutates the original persianDate by setting it to the start of a unit of time.

persianDate().startOf('year');   // set to Farvardin 1st, 12:00 am this year
persianDate().startOf('month');  // set to the first of this month, 12:00 am
persianDate().startOf('week');   // set to the first day of this week, 12:00 am
persianDate().startOf('day');    // set to 12:00 am today
persianDate().startOf('hour');   // set to now, but with 0 mins, 0 secs, and 0 ms
persianDate().startOf('minute'); // set to now, but with 0 seconds and 0 milliseconds
persianDate().startOf('second'); // same as persianDate().milliseconds(0);

These shortcuts are essentially the same as the following.

persianDate().startOf('year');
persianDate().month(0).date(1).hours(0).minutes(0).seconds(0).milliseconds(0);

persianDate().startOf('hour');
persianDate().minutes(0).seconds(0).milliseconds(0)

End of Time

persianDate().endOf(String);

Mutates the original persianDate by setting it to the end of a unit of time.

This is the same as persianDate#startOf , only instead of setting to the start of a unit of time, it sets to the end of a unit of time.

persianDate().endOf("year"); // set the persianDate to 12-31 11:59:59.999 pm this year

Display

Once parsing and manipulation are done, you need some way to display the persianDate.

Format

persianDate().format();
persianDate().format(String);

This is the most robust display option. It takes a string of tokens and replaces them with their corresponding values.

persianDate().format("dddd, MMMM DD YYYY, h:mm:ss a"); // "شنبه, اردیبهشت ۲۱ ۱۳۹۲, ۰:۴۲:۴۷ ق ظ"
persianDate().format("dddd, hA")//"شنبه, ۸ ق ظ"

There are a couple conventions used with the naming of the

Default format

ISO8601 format YYYY-MM-DDTHH:mm:ssZ "۱۳۹۱-۱۰-۰۴ ۱۱:۲۷:۵۳ ق ظ"

Format To Persian date

By Default persianDate format, use Persian Number System, for engilsh number Set formatPersian Option as false

var d = new persianDate([1391]);
d.format(); //"۱۳۹۱-۰۱-۰۱ ۰۰:۰۰:۰۰ ق ظ"
window.formatPersian = false;
d.format(); //"1391-01-01 00:00:00 AM"

Also you can set golbal config like this

window.formatPersian  = false

Note: After Set Golbal config you can set config for every instance

var d = new persianDate([1391]);
d.format(); //"۱۳۹۱-۰۱-۰۱ ۰۰:۰۰:۰۰ ق ظ"
window.formatPersian = false;
d.format(); //"1391-01-01 00:00:00 AM"
d.formatPersian = true;
d.format(); //"۱۳۹۱-۰۱-۰۱ ۰۰:۰۰:۰۰ ق ظ"

Difference

persianDate().diff(PersianDate|String|Boolean);
persianDate().diff(PersianDate|String|Boolean);

To get the difference in milliseconds, use persianDate#diff like you would use persianDate#from .

var a = persianDate([1392, 0, 29]);
var b = persianDate([1392, 0,28]);
a.diff(b) // 86400000

To get the difference in another unit of measurement, pass that measurement as the second argument.

var a = persianDate([1392, 0,29]);
var b = persianDate([1392,0,28]);
a.diff(b, 'days')// 1

The supported measurements are years, months, weeks, days, hours, minutes, and seconds. For ease of development, the singular forms are supported .

var a = persianDate([1391, 0]);
var b = persianDate([1392, 5]);
a.diff(b, 'years')       // 1
a.diff(b, 'years', true) // 1.5

If the persianDate is later than the persianDate you are passing to persianDate.fn.diff , the return value will be negative.

var a = persianDate();
var b = persianDate().add('seconds', 1);
a.diff(b) // -1000
b.diff(a) // 1000

A easy way to think of this is by replacing .diff( with a minus operator.

          // a < b
a.diff(b) // a - b < 0
b.diff(a) // b - a < 0

Unix Offset (milliseconds)

persianDate().valueOf();

persianDate#valueOf simply outputs the number of milliseconds since the Unix Epoch, just like Date#valueOf .

persianDate(1318874398806).valueOf(); // 1318874398806
persianDate(1318874398806); // "۱۳۹۰-۰۷-۲۵ ۲۱:۲۹:۵۸ ب ظ"

To get a Unix timestamp (the number of seconds since the epoch) from a persianDate , use persianDate#unix .

Unix Timestamp (seconds)

persianDate().unix();

persianDate#unix outputs a Unix timestamp (the of seconds since the Unix Epoch).

persianDate(1318874398806).unix(); // 1318874398

This value is floored to the nearest second, and does not include a milliseconds component.

Timezone Offset

persianDate().zone();

Get the timezone offset in minutes.

persianDate().zone(); // (60, 120, 240, etc.)

Days in Month

persianDate().daysInMonth();

Get the number of days in the current month.

persianDate([1392,01]).daysInMonth() // 29
persianDate([1392,08]).daysInMonth() // 31

As Javascript Date

persianDate().toDate();

To get the native Date object that persianDate.js wraps, use persianDate#toDate .

This will return the Date that the persianDate uses, so any changes to that Date will cause the persianDate to change. If you want a Date that is a copy, use persianDate#clone before you use persianDate#toDate .

As Array

persianDate().toArray();

This returns an array that mirrors the parameters from new persianDate() .

persianDate().toArray(); // [1391, 1, 4, 14, 40, 16, 154];

Is Leap Year

persianDate().isLeapYear();

persianDate#isLeapYear returns true if that year is a leap year, and false if it is not.

persianDate([1391]).isLeapYear() // true
persianDate([1392]).isLeapYear() // false

Is Daylight Saving Time

persianDate().isDST();

persianDate#isDST checks if the current persianDate is in daylight savings time.

Note: Daylight saving time in Iran

persianDate([1392, 2, 12]).isDST(); // true
persianDate([1392, 7, 14]).isDST(); // false

Is a PersainDat

persianDate().isPersianDate(obj);

To check if a variable is a persianDate object, use persianDate().isPersianDate() .

persianDate().isPersianDate() // false
persianDate().isPersianDate(new Date()) // false
persianDate().isPersianDate(persianDate()) // true
