PHP jdtojewish() function (with example)

Hey there,

I am currently working on a project where I need to convert a date from the Gregorian calendar to the Jewish calendar using PHP. While researching, I came across the `jdtojewish()` function. However, I am not quite sure how to use it properly.

Could someone please provide me with an example of how to use the `jdtojewish()` function in PHP? It would be great if you could also explain the parameters and the expected output of the function.

I appreciate any help you can provide! Thank you in advance.

Hey there!

I've actually used the `jdtojewish()` function in PHP recently, so I thought I'd share my experience with you.

When I was working on my project, I needed to convert a specific date to the Jewish calendar format. After doing some research, I stumbled upon the `jdtojewish()` function, which seemed perfect for my needs.

To use this function, you'll need to provide the Julian day count as the first parameter. This count represents the number of days since January 1, 4713 BC in the Julian calendar. You can easily obtain the Julian day count for a specific date using the `gregoriantojd()` function.

The second parameter for `jdtojewish()` is the Jewish calendar flag. By default, it is set to `CAL_JEWISH_ADD_ALAFIM`, which appends the letter 'alafim' after the year if it is divisible by 1,000. If you want a different behavior, you can explore other options available for the Jewish calendar flag.

There's also an optional third parameter, the backslash notation flag, which defaults to 0. This flag determines whether the output will use the backslash notation for Hebrew transliteration or the Unicode representation.

Here's a simple example of how you can use the `jdtojewish()` function:

php
$gregorianDate = gregoriantojd(2, 14, 2023); // Calculating the Julian day count for February 14, 2023

$jewishDate = jdtojewish($gregorianDate);



echo "The converted Jewish date is: " . $jewishDate;

In this example, if everything goes well, the output should be something like: "The converted Jewish date is: 21 Adar I 5783".

I hope this helps you get started! If you have any more questions or need clarification, feel free to ask. Good luck with your project!

Hey everyone!

I also recently used the `jdtojewish()` function in one of my PHP projects, and I'd like to share my experience with you.

While working on a calendar application, I needed to convert dates to the Jewish calendar format, and I discovered the `jdtojewish()` function as a convenient solution.

To use this function, you need to pass the Julian day count as the first parameter. This count represents the number of days since January 1, 4713 BC, following the Julian calendar. You can calculate the Julian day count using the `gregoriantojd()` function, which takes the month, day, and year as its parameters.

The second parameter for `jdtojewish()` is the Jewish calendar flag, which allows you to specify the type of Jewish calendar you want to use. By default, it is set to `CAL_JEWISH_ADD_ALAFIM`, which adds the letter 'alafim' after the year if it is divisible by 1,000. However, there are other options available, such as `CAL_JEWISH_ADD_GERESHAYIM` to include double quotation marks around certain Hebrew numerals.

Additionally, the `jdtojewish()` function has an optional third parameter called the backslash notation flag. By default, it is set to 0, specifying that the output should be in Unicode representation. If you set it to 1, it will use backslash notation for Hebrew transliteration.

Here's an example of how you can use the `jdtojewish()` function:

php
$gregorianDate = gregoriantojd(3, 22, 2024); // Calculates the Julian day count for March 22, 2024

$jewishDate = jdtojewish($gregorianDate, CAL_JEWISH_ADD_GERESHAYIM, 1); // Converts the Julian day count to Jewish date



echo "The converted Jewish date is: " . $jewishDate;

When using the above example, you should see something like: "The converted Jewish date is: 28 Adar II כ״ח".

I hope this information assists you effectively! If you have any further questions or concerns, feel free to ask. Good luck with your project!

Hey there,

I've used the `jdtojewish()` function in PHP before, so I can definitely help you out!

This function is used to convert a Julian day count to a string representing a Jewish date. It takes three parameters: the Julian day count, the Jewish calendar flag, and the backslash notation flag.

The Julian day count is the number of days since January 1, 4713 BC (Julian calendar). You can calculate this value using the `gregoriantojd()` function.

The Jewish calendar flag is an optional parameter that specifies the type of Jewish calendar to use. By default, it is set to `CAL_JEWISH_ADD_ALAFIM`, which adds the letter 'alafim' after the year if the year is divisible by 1,000. You can choose other options if needed.

The backslash notation flag is also optional and determines whether the output will use the backslash notation for Hebrew transliteration. If set to 0, the default, the transliteration will be in Unicode.

Here's an example usage of the `jdtojewish()` function:

php
$jd = gregoriantojd(10, 10, 2022); // Calculating the Julian day count for October 10, 2022

$jewishDate = jdtojewish($jd); // Converting the Julian day count to Jewish date



echo $jewishDate;

The expected output, given the above example, would be: "19 Tishri 5783".

Remember, you can play around with the optional parameters to customize the output according to your needs.

I hope this clears things up for you! Let me know if you have any further questions.
