Bible Birthday Calculator

Modern Birthday calculations are determined by using the date of someone's birth and watching for the recurrence of that date each year. The modern system does not work well for leap day births, but since leap days do not occur very often the leaps are ignored. On the Bible's calendar, Birthdays should be calculated differently. Life is a form of covenant between God and each person, so "Bond-Man" calculation is implied. This page provides an interactive birthday calculator as well as some thoughts on the significance of the system.

To start this discussion, enter the birthday for the person in question, using the modern Gregorian calendar. The results will be added to this page, displaying all birthdays from the 1st through 121st, the Biblical limit on modern life lengths. Discussion of the results follow below.

Background

Our "Birth Day" is the day we first draw breath. The Hebrew word for breath is also the word for Spirit, and our hope is that besides air itself, that we will eventually receive the Holy Spirit. At that point we have proof of salvation and the hope of everlasting life.

The basis for understanding what is happening at someone's birth comes from thinking about life itself as a covenant. It was God himself who formed the child in the womb, and God himself holds all life in his hands. We return to him when we die. These Bible truths taken together form one of the most simple covenants of all. A covenant of life.

Generally speaking, covenants are measured in full years, and the natural time for reviewing our life covenant between God and ourselves is thus at full year intervals from our first day, what we call our birthday.

Because of the structure of the calendar God uses for measuring time, the simple recurring month/day pairs from someone's calendar day of birth do not reflect time measured as part of a covenant. Matching the month/day pair of our day of birth does not synchronize with our personal life covenant.

The Bible uses the term "Bond-Man" counting to indicate the way time is measured in a covenant. Simply stated, "Bond-Man" counting uses a new calendar, with an epoch started at the day the covenant comes into force. Years, months and days in that covenant are measured against that calendar.

The "AA" calendar is an example where Adam's first day is the starting Epoch. It continues as the system God uses for measuring time in Adam's race. Bond-Man counting is simply a personal application of this same system.

Notes On Leaps

People born on February 29 have difficulty with modern birthdays because their day only comes around once every 4 years.

The Bible's calendar has entire leap months, 30 days each, inserted into every Sabbath and Jubilee year. At first glance this seems to mean that many more people would be impacted by births on leaps and thus miss their birthday.

This turns out not to be a problem at all because this system uses "bound-man" counting. Even when someone is born on a leap month, their future birth dates are computed on a freshly starting calendar, because they are starting a fresh covenant, without need to reference the actual calendar months going by.

It is also the case that everyone observes their personal Sabbaths and Jubilees at their appointed Sabbath and Jubilee year points.

Notes on the term Covenant

When someone accepts Jesus as savior they enter into what the Bible calls the New Covenant. A common observation found in Christians is that they can later look back and see that Jesus was active in their life even before they were saved. As Jeremiah was told, "I knew you before you were formed in the womb."

The idea that under girds the dates calculated on this page is that everyone alive is joined to God in a simpler covenant, a life covenant. That earlier, and simpler covenant provides the foundation for understanding what these Christians commonly see. We know that God wishes all to come into relationship with him, and that wish may be expressed through an annual review with the King himself, saved or not.

Notes on Month of Birth

Modern horoscopes also appear to be a fallen form or degeneration of a Biblical truth, that something about the time of birth has bearing on the nature of someone's life or life call. This is similar in concept to the idea that someone's name, if not changed by God himself, has bearing on the spiritual makeup of a person.

The Bible Month of the birth date itself may thus also explain how someone is gifted in their walk with Jesus. Each month maps to a different Patriarch, Tribe, and Apostle. They also map to various other things including temple articles, commandments, Egyptian plagues and so on. Use the first date in the table above for determining the month of birth, and thus the tribal affiliation based on time.

Notes on Premature Birth

In our modern era there are technological miracles that can rescue children born at very early stages of development. The question comes up, does this impact their birthdates?

The idea is that the first day a child draws breath is the significant birth date. The Hebrew term for breath is also the term for Spirit, as in Holy Spirit. Just as a new born breaths in air at the time of their physical birth, so too, can we start to receive or "breath in" the Holy Spirit when we are born again.

So the timing of everything that will hopefully lead to receiving the Holy Spirit, seems to begin at first breath, even when the child is premature.

Notes On Calculation Complexity

This page provides a complete view of 120 years of presentation dates given a starting birth date. The use of a computer appears to make this calculation dependent on the availability of a computer in order to calculate the dates.

The question thus arises, Isn't this too complex for observation in the pre-computer era?

The answer to this is no. Just as people today know their age even when it is not their birthday, the knowledge of someone's age determines how many days to their next birthday. Calculation on paper calendars is simple, and simple enough for most people to compute mentally if the calculation is done at their birthday and headed for the next birthday.

Because these intervals are always whole numbers of Biblical months, the day of the month is always the same for every birthday throughout someone's life. What varies each time is the month of the year.

For Further Study

This same system can be used to track general covenants, not just life covenants. If someone is under a specific time interval, say 7 years of punishment, and if the first day can be established, then the final date will be at what is listed as the 8th birthday listed in the chart above.

Examples to try:

  • Fall of Baghdad The US Army invaded Baghdad in April of 2003. The end of the "Battle of Baghdad" was on April 12, 2003. This was the prophetic start of a "7 times" punishment interval on the United States. (The day for a year replay of going to Babylon.) It was also the public start of the Tribulation. This interval is thus up after 7 biblical years. (ie, it ends on day 1 of year 8.) To compute the interval enter the fall of Baghdad in the form above, and show 8 years. The 8th year is the last year shown if you've asked to view 8 years. That year starts on the first day after the 7 years are up. President Obama has said he intends to have the US Army out of Iraq in 16 months from taking office in January of 2009. Do they agree? Will it happen as planned?

  • US Constitutional Government The US government began operations under the newly ratified constitution on March 4, 1789. Type the date in above, and view 221 years. This interval is two times the number of floors in the World Trade Center towers. Joseph, one of the Patriarchs for the United States (Manasseh being the other) lived a Biblical 110 years. Manasseh was the double portion holder from the set of promises given to Abraham, so 110 years is doubled. Note that the Plague on Cattle includes the passage of TARP in early October of 2008, what many felt was the 110 page end of constitutional government.

As a general rule anyone operating under a Biblically mandated covenant interval measured in years will see that covenant over on the first day of the first year after that covenant interval expires. This tool can be used to easily measure those intervals. Fulfillment headlines in the news, and personally, are often dramatic and sudden.

If you've been given a personal prophetic interval measured in days, enter the start date for that interval as a birthday in the form above. View 1 more than the total number of years in the interval. The resulting form will show when the interval is over.
