Your dates are wrong for Nissan 1 and Passover Chag Hamatzot

Miriam 7 months ago updated by Michael J. Radwin 7 months ago 2

Your calendar dates for the new month are innacurate as it is impossible scientifically for anyone to have seen the moon on March 29th as it is a day where the moon is hidden. The next day on the 30th-31st, the new crescent moon would be visible or the day after that should there have been clouds in the sky, but your and the Rabbis Hillel II calculation are against the books of Moses and God, as one cannot change time based on a calculation nor change the moon's position (not seeing the moon is different), however proclaiming the start of the month when it would not AT ALL be possible is against Torah. If there are disputes we are to ask the authorities. Deuteronomy 17:8–13 but is that always true? Would we ask Korach and his followers who were swallowed by the Earth for going against Moses and God? The crescent moon is the sign of the new month, and no rabbi, no matter how distinguished has the power to change that, as unlike God, he cannot move the moon. This year the Rabbis have miscalculated the date for Passover. They did so because they incorrectly determined the start of the month to be from March 29th night to March 30th day with their Hillel II calendar. This is impossible. Why? Well if you look at an astronomical calendar, you will see that the moon is not visible from Jerusalem then (even when standing on Mt Moriah. Why? Because it's between the Earth and the sun with it's lighted portion facing away. For the Rabbis to contradict God and the books of Moses, it's no different from Korach. Abraham was the Ivri, who stood out against the masses who worshipped idols. The Levites stood up against those who worshipped the golden calf. In the book of Judges, Judges stood up against the lunacy of the elders who worshipped their false gods along with God. Not all leaders are good. Jews were persecuted throughout centuries because of these false leaders who led the people astray. Moses wrote down HaKol (everything). These corrupt leaders attempt to overwrite his instructions with their numerous false books and changing the calendar. Israel became a country in 1948. Since that time, they had the opportunity to build the temple in thanks to God, but they would rather follow their made-up calendar and made up traditions. They do not have the power to change the date of the new month based on calculation that conflicts with nature. Seeing or not seeing the moon is differenrt, but if the moon is not scientifically visible from earth on the day they claim is the 1st of Nissan, it's not the 1st of the 1st month. The real first of the month is March 30-31 The feast of unleavened bread is supposed to run from the 13th evening to the 20th evening, but in Israel where they don't add an extra day, they will end it the 19th, and eat chametz on the 20th when it's still Passover. It is also a sin to add or subtract from torah, and by them eating unleavened bread of the 12th (they falsely proclaim the holiday to start then), they are adding to Torah. It's only a matter of time before God brings them to justice. If one keeps his covenant, they get a blessing, and if they don't a curse. None of us are perfect, but for a whole people to call themselves the chosen people, and then to go along with corruption like this, is disloyal to God. The first commandment is to know God is your God. God's law is above man's law, and if their made up laws contradict the books of Moses, then they are not to be followed, and one should flee like Lot who was rescued by the angels from Sodom. It is foolish to attach the name of Korach to your religious sect, if Korach will be consumed in fire. These rabbis are clearly wrong and if one believes in God and the books of Moses, it says God will punish them.

Request 24 Hour clock format

רב-גל 8 months ago updated by Michael J. Radwin 8 months ago 2

Please advise how to get ALL time presentation in 24 hour format

Answer
Michael J. Radwin 8 months ago

Thanks for contacting Hebcal.


The time format on the Hebcal.com website is specific to a location. Some countries such as Israel use 24 hour format. Other locations like the United States, Canada or Brazil use a 12 hour format.

If you wish to have more control over how Hebcal events are displayed, we would encourage you to download the Hebcal events to another application (Google Calendar, Apple Calendar, Microsoft Outlook, etc.) and then format the calendar as you see fit.

Daily parsha

nysolutions 8 months ago updated by Michael J. Radwin 7 months ago 3

Is there any way to get the day and parsha from the hebrew calendar api? example ג' כי תשא

Answer
Michael J. Radwin 7 months ago

The only web API that we have that shows the upcoming Shabbat's parasha haShavua every single day of the week is the Hebrew Date Converter REST API.

From the URL you posted, it looks like you are hoping to use the Jewish calendar REST API. Unfortunately, this API does not support looking up the weekly Torah portion every day of the week.

If you wish to use the Jewish calendar REST API to look up the weekly Torah portion, you will need to specify the date of Shabbat (for example, this week 2024-03-15) and not today's day.

You can also use the Leyning (Torah Reading) API to get the full kriyah leyning on Shabbat and holidays, Triennial (optionally) for Shabbat, and weekday readings on Mondays & Thursdays. However, this API would not return the weekly Torah portion on a Tuesday because there is no Torah reading on a typical Tuesday.

    Multiple issues regarding the Shabbat Rest API

    Yoni Shachar 8 months ago updated by Michael J. Radwin 7 months ago 8

    1. I was surprised to discover that the API returns way more info than the Candle Lighting and Havdalah dates - I managed to extract these dates by iterating through the items array and checking the title_orig field, but is this the intended way?

    2. Is there a way to know the next Shabbat info on Saturday? I attempted around 10 PM but got the current info.

    Answer
    Michael J. Radwin 8 months ago

    Weekly calculations change every Sunday at midnight in the city’s local time zone.


    The returned JSON results includes a list of items that have a category will typically include each of the following:

    • candles – Candle-lighting on Friday or erev chag
    • parashat – Parashat HaShavua, the weekly Torah portion
    • havdalah – Havdalah, the end of Shabbat

    Depending on the week of the year, other items may appear in the results, including

    • holiday (with subcat major or minor or fast)
    • zmanim (often with subcat fast for “Fast begins” or “Fast ends”)


    This API uses a similar URL and response format as our full Jewish calendar REST API, but offers less control over the dates and times. If you find you want more fine-grained control over the date ranges, or what kinds of events are included and which are excluded, we recommend using the full Jewish calendar REST API instead.

    "Show Hebrew date for dates with some event" shouldn't trigger for Daily Learning

    ymshulman 8 months ago updated by Michael J. Radwin 8 months ago 2

    Daily Learning is incredibly helpful. Hebrew dates only showing when it's a Holiday of some sort (Rosh Chodesh, Yamim Tovim, etc - just to not have the overload of dates every weekday) is also helpful. 
    The current setting "Show Hebrew date for dates with some event" shows even if one has Daily Learning set to show. Would that behavior be able to be tweaked? Or is there a way to add a setting in a way that isn't complicated?
