In order to avoid abuse/crashes, some limits have been placed on the length of the periods. If any values have been inserted in the target fields, the period covered cannot exceed 2501 years. If the target fields are left empty, the period covered cannot exceed 130 years.
The Core number refers to the central number in the golden bubble, which also correponds to the Solar Plexus chakra. Thus, the Solar Plexus chakra is not listed separately in the chakras list, as they are one and the same.
The Destiny number corresponds to the so-called General Purpose or Spiritual Harmony number, which is the sum of the Purpose and Social numbers.
The Core and Purpose numbers are often the same but not always. The Purpose number matures over the first 40 years of life. My intuition says that people where the Core and Purpose numbers are the same, it takes them 40 years to truly discover themselves as that number, or grow into it, to develop their core number. For people where the Purpose is different from the Core number, they are born with their core number already developped, and they work for 40 years on developing the Purpose number.
The Chakra numbers are shown in the format: π18β20. The first number is the Energy or Spiritual Chakra, which is the one found on the vertical axis. The second number is the Physical/Manifestation of the Chakra, on the horizontal axis. The reason for the special character (π in this example) is that such a unique identifier allows for you to copy any combination that is of interest, for example π18β20 and search through the table with the built in browser search, allowing you to highlight that number across a very large table, as well as get a count of how many are present, without having to build more complicated code solutions.
You can exclude dates that have a specific number in any of the four main fields (Core, Purpose, Social, Destiny).
To do this, simply add a dash (a minus sign, "-") before the number you want to exclude.
-11 into the "Core #" field.You can use this for any of the four fields, and you can even combine it with other searches.
