Bulls & Goats

The Bulls & Goats Calculator calculates how many public sacrifices would have been offered on your behalf if the Jewish temple were around today and we were under the Old Covenant. All the various sabbaths, holy days, festivals, etc. are taken into consideration. It does not factor in free-will offerings — only scheduled, public sacrifices offered on behalf of all people. Simply enter in your birth date below and click the “Show Me” button. You can leave the “Until” field as-is unless you want to play around with dates.

    Are you sure this is accurate? My number of required sacrifices is 51,485. But I’ve only been alive for 10,904 days. This means I had to sacrifice 4.72 animals every day of my life. Every Jew, hundreds of thousands of them, all sacrificed five animals per day? In a twenty-four hour period one priest could only cover 113 people (4.72*24), and that’s if he worked straight through with no break for the full twenty-four hour day. The line to kill your goat would be worse than the DMV!

      I’m confident it is accurate. Note that the number of sacrifices (51k in your case) are the *public* sacrifices offered — ie the ones that the priests would have offered during your lifetime. They are not sacrifices that individuals would have been lining up at the Temple to *give* to the priests (those are “free will” offerings). The public offering were made on behalf of the entire nation of Israel. It does *not* mean that 51k sacrifices would have been offered for *each* 30 year old individual.

      This tool is meant to show how many public offerings were made during one’s lifetime and that those sacrifices were intended to atone for your sins (and the rest of the nation’s).

      If you look at the Results tab, it breaks down what sacrifices would have been made. In your case, you should around 21k daily sacrifices, 3100 sabbath sacrifices, etc. That means that during your ~30 years of life, the priests would have offered 21k daily sacrifices (2 per day for 10k+ days), 3100 Sabbath sacrifices (two lambs per week on the Sabbath), etc. on behalf of the nation of Israel, which would have included you.

      Thanks for stopping by!

      In Christ

        Thanks for clarifying that it’s public offerings. It’s a staggering number that is just a pittance compared to the ultimate sacrifice Once, for all…Praise God for Jesus!

    Your new moon calculation is incorrect. The sacrifices are once a month, but your calculation computes it as once a week.

      Good catch! Fixed. Thanks!


      • Adam Krolnik September 18, 2013 at 5:17 pm #

        Still seeing too many new moon counts for date range of 1/1/1 – 1/15/1.

        I get 0 for that date range, which is probably right. You may need to clear your cache to get the new Javascript file.

    Think about the cost in dollars. Very high , but still not able to pay for my sin. How long I tried to be “good” and earn my way. Thanks be to God for HIS salvation.

    I have an ESV Study Bible and checked the website link too for the public sacrifices chart and am having difficulty locating it. Could you reference a page number for me?

    thanks, Hester

    • Tom January 8, 2014 at 8:38 pm #

      Hi Hester,

      In my ESV Study Bible, the main chart is on page 310, entitled “Calendar of Public Sacrifices.” It is a supplement to the notes on Numbers 28-29.

      Hope that helps!

      • Hester Christensen January 9, 2014 at 5:23 pm #

        Thank you! I just found it! :)

    Is there a way to figure out how much a family line (roughly) owed since crucifixion ?

    • Tom April 7, 2015 at 10:21 am #

      Interesting question. That would require more “math” than what it does right now. I just did a start date of 4/1/100, which is the farthest it can go back before it thinks double-digit numbers are for this century (e.g. if I put in 4/1/33, it thinks I mean 4/1/2033). 4/1/100 yields 2,474,039 sacrifices. That’s a “rough” estimate for 1 person.

      You could use that to extrapolate out lineage, using an assumed birth rate and maybe an average “sacrifices per year per person.” You could do it, but it’s more than this tool provides. Let me know what you come up with!

      Thanks for stopping by.
