## 4-2- convert(calendar:Calendar, locale?:Locale)
If you use the convert method without argument, the date will be converted to Gregorian calendar.
The second argument (Locale) is optional.
```javascript
import DateObject from "react-date-object";
import gregorian from "react-date-object/calendars/gregorian";
import persian from "react-date-object/calendars/persian";
import arabic from "react-date-object/calendars/arabic";
import indian from "react-date-object/calendars/indian";
var date = new DateObject();
console.log(date.format()); //2020/10/31
date.convert(persian);
console.log(date.format()); //1399/08/10
date.convert(arabic);
console.log(date.format()); //1442/03/14
date.convert(indian);
console.log(date.format()); //1942/08/09
date.convert(gregorian); //or date.convert()
console.log(date.format()); //2020/10/31
```
## 4-3- format(token:String)
default format is YYYY/MM/DD.
to see all format types click [here](#5--Formatting-Tokens)
```javascript
import DateObject from "react-date-object";
var date = new DateObject();
consoel.log(date.format()); //2020/10/31
consoel.log(date.format("MM/DD/YYYY")); //10/31/2020
consoel.log(date.format("MMM/DD/YYYY HH:mm:ss")); //Oct/31/2020 18:17:28
consoel.log(date.format("dddd DD MMMM YYYY, hh:mm:ss A")); //Saturday 31 October 2020, 06:19:18 PM
consoel.log(date.format("ddd DD MMM YYYY, hh:mm a")); //Sat 31 Oct 2020, 06:20 pm
```
### formatting with ignore list:
```javascript
import DateObject from "react-date-object";
var date = new DateObject();
console.log(
date.format("hours:HH minutes:mm seconds:ss", ["hours", "minutes", "seconds"])
); //hours:12 minutes:22 seconds:40
console.log(date.format("it's HH o'clock", ["it's", "o'clock"])); //it's 12 o'clock
console.log(
date.format(`DD MMMM at hh:mm ${date.hour >= 12 ? "Afternoon" : "Morning"}`, [
"at",
"Afternoon",
"Morning",
])
); //11 November at 12:22 Afternoon

var date = new DateObject();
date._format = "dddd DD MMMM YYYY";
date.parse("Monday 24 August 2020");
console.log(date.format("YYYY/MM/DD")); //2020/08/24
date.parse("Friday 07 August 2020");
console.log(date.format("YYYY-MM-DD")); //2020-08-07
date
.setCalendar(persian)
.setLocale(persian_en)
.setFormat("YYYY/MM/DD")
.parse("1399/06/03");
console.log(date.format()); //1399/06/03
date.setFormat("YYYY/MM/DD HH:mm").parse("1399/06/03 12:32");
console.log(date.format("dddd DD MMMM @ hh:mm a")); //Doshanbeh 03 Shahrivar @ 12:32 pm
```

calendar: arabic,
locale: arabic_ar,
});
console.log(date.getValue("M")); //1
console.log(date.format("M")); //١
console.log(typeof date.getValue("D")); //number
console.log(typeof date.format("D")); //string
console.log(Number(date.getValue("YYYY"))); //1442
console.log(Number(date.format("YYYY"))); //NaN

## 4-12- custom months, week days & digits
See the example below in case you want to use your personal data instead of default months, week days & digits
```javascript
import DateObject from "react-date-object";
var date = new DateObject();
console.log(date.format("MMMM MMM")); //November Nov
console.log(date.format("dddd ddd")); //Monday Mon
console.log(date.format("D")); //2
date.months = [
["jan", "j"], //[["name","shortName"], ... ]
["feb", "f"],
["mar", "m"],
["apr", "a"],
["may", "m"],
["jun", "j"],
["jul", "j"],
["aug", "a"],
["sep", "s"],
["oct", "o"],
["nov", "n"],
["dec", "d"],
];
date.weekDays = [
["su", "s"], //[["name","shortName"], ... ]
["mo", "m"],
["tu", "t"],
["we", "w"],
["th", "t"],
["fr", "f"],
["sa", "s"],
];
/**
* This is just a test to display digits.
* The Greek number system does not work like this.
*/
date.digits = ["", "I", "II", "III", "IV", "V", "VI", "VII", "VIII", "IX"];
console.log(date.format("MMMM MMM")); //nov n
console.log(date.format("dddd ddd")); //mo m
console.log(date.format("D")); //II
console.log(date.month);
/**
*{
* name: 'nov',
* shortName: 'n',
* length: 30,
* index: 10,
* number: 11,

*/
console.log(date.weekDay);
/**

console.log(date.digits);
/**
* [
* '', 'I', 'II',
* 'III', 'IV', 'V',

```
You can use `date.setMonths(months).setWeekDays(weekDays).setDigits(digits)` as well
