Hebdate

Version Status

Hebdate is a simple library that lets you easily convert gregorian dates to jewish dates, and vice versa, using several formats.

Installation

Install the package via composer:

composer require kfirba/hebdate

Basic Usage

Let's convert some dates:

// Note that we should pass the date as dd/mm/yyyy format:
GregorianDate::toJewish([5, 6, 2016])->convert();
// -> 28 9 5776
GregorianDate::toJewish('05/06/2016')->convert();
// -> 28 9 5776
GregorianDate::toJewish(Carbon::createFromDate(2016, 6, 5))->convert();
// -> 28 9 5776
GregorianDate::toJewish(new DateTime('2016-06-05'))->convert();
// -> 28 9 5776

Naturally, we can use it vice versa:

GregorianDate::fromJewish('28 9 5776')->convert();
// -> 05/06/2016
GregorianDate::fromJewish('28 Iyar 5776')->convert();
// -> 05/06/2016
GregorianDate::fromJewish('כח אייר התשעו')->convert();
// -> 05/06/2016
GregorianDate::fromJewish('כח׳ אייר התשע״ו')->convert();
// -> 05/06/2016

Actually, behind the scenes we are using two classes which you can choose whichever you want to use, the GregorianDate class and the JewishDate class.

By calling GregorianDate::fromJewish(), you actually new up a JewishDate instance. So it's identical to:

JewishDate::toGregorian('28 9 5776')->convert();
// -> 05/06/2016

As you may have guessed, you can also call:

JewishDate::fromGregorian('05/06/2016')->convert();
// -> 28 9 5776

Input

As we have seen before, the classes are accepting different input formats:

  • GregorianDate::toJewish(INPUT_TYPE):

    1. Array - A plain PHP array that represents the date in [dd, mm, yyyy] format.
    2. String - A string of a gregorian date in the format of mm/dd/yyyy. The delimiter may be a slash(/), a dot(.) or a dash(-). For example: 05-06-2016.
    3. Carbon Object - Any Carbon object.
    4. DateTime Object - Any DateTime object.
  • JewishDate::fromGregorian(INPUT_TYPE):

    1. Has the same options as GregorianDate::toJewish(INPUT_TYPE) as it's just an alias.
  • JewishDate::toGregorian(INPUT_TYPE):

    1. Array - an array that contains a hebrew date in [dd, mm, yyyy] format.
    2. Numeric String - A numeric string in "dd mm yyyy" format (note that the delimiter has to be a space). For example, 28 9 5776.
    3. English month numeric string - A numeric string with english month name. For example, 28 Iyar 5776.
    4. Full hebrew date string - A full hebrew string without any punctuation. For example, כח אייר התשעו.
    5. Full hebrew date string with punctuation - A full hebrew string with punctuation. For example, כח׳ אייר התשע״ו.
  • GregorianDate::fromJewish(INPUT_TYPE):

    1. Has the same options as JewishDate::toGregorian(INPUT_TYPE) as it's just an alias.

Output

We can also specify which output format we want for the date. To do so, we just need to chain the format() method and supply it with a format.

Note that the format constants are under Kfirba\Formats\Format class.

Jewish Date Formats:

GregorianDate::toJewish('05/06/2016')->format(Format::NUMERIC)->convert();
// The default format -> 28 9 5776
GregorianDate::toJewish('05/06/2016')->format(Format::ENGLISH_MONTH)->convert();
// -> 28 Iyar 5776
GregorianDate::toJewish('05/06/2016')->format(Format::HEBREW_FULL)->convert();
// -> כח אייר התשעו
GregorianDate::toJewish('05/06/2016')->format(Format::PRESENTABLE_HEBREW_FULL)->convert();
// -> כח׳ אייר התשע״ו

// These formats also apply when using the JewishDate::fromGregorian() constructor:

JewishDate::fromGregorian('05/06/2016')->format(Format::NUMERIC)->convert();
// The default format -> 28 9 5776
JewishDate::fromGregorian('05/06/2016')->format(Format::ENGLISH_MONTH)->convert();
// -> 28 Iyar 5776
JewishDate::fromGregorian('05/06/2016')->format(Format::HEBREW_FULL)->convert();
// -> כח אייר התשעו
JewishDate::fromGregorian('05/06/2016')->format(Format::PRESENTABLE_HEBREW_FULL)->convert();
// -> כח׳ אייר התשע״ו

Gregorian Date Formats:

JewishDate::toGregorian('28 9 5776')->format(Format::NUMERIC)->convert();
// The default format -> 05/06/2016
JewishDate::toGregorian('28 9 5776')->format(Format::CARBON)->convert();
// -> Carbon Object {}
JewishDate::toGregorian('28 9 5776')->format(Format::DATETIME)->convert();
// -> DateTime Object {}

// These formats also apply when suing the GregorianDate::fromJewish() constructor:

GregorianDate::fromJewish('28 9 5776')->format(Format::NUMERIC)->convert();
// The default format -> 05/06/2016
GregorianDate::fromJewish('28 9 5776')->format(Format::CARBON)->convert();
// -> Carbon Object {}
GregorianDate::fromJewish('28 9 5776')->format(Format::DATETIME)->convert();
// -> DateTime Object {}

Extras

The convert() method accepts a $delimiter argument. When converting to Jewish dates it defaults to a space (" ") and when converting to Gregorian date it defaults to a slash (/).

The library also registers 2 global functions:

  1. utf8_str_split($str = '', $len = 0) which acts the same as PHP's str_split function but works on UTF8 strings.
  2. isJewishLeapYear($year) which determines whether the given year is a leap year. Note that the year has to be numeric and greater than 5000.
