Each section is named after the famous constellations or zodiac signs that we are all familiar with (i.e Aries, Leo, Gemini, …). Visually a chart is a 360 degree wheel divided into 12 sections. The location, date, and time of your birth is all that is needed to calculate your birth chart. Every individual’s birth chart (also know as a natal chart) is completely unique. Seconds = Format(((Minutes - Int(Minutes)) * 60), "0.Think of it like a map that provides a snapshot of all the planetary coordinates at the exact time of your birth.

The direction values (deg, min, sec) are formatted as text. Here are two macros that do the job for my astronomy spreadsheet. Just make sure the cell this formula goes in has normal formatting - not time: =A1*24Īlternatively, you can also extract specific components from the time value by using the following: =INT(A1*24) returns degrees
If you need to convert this value in to a decimal degrees value, you just need to multiply by 24, because a "day" in Excel time format has a value of 1 (so an hour is 1/24th, etc). However, this will only work if the final result is positive Excel will not will render negative times.
These can be added together, etc, as necessary (they are just numbers underneath, after all). If you'd like leading zero's then just double-up each letter. The prevents the hour resetting to zero as it reaches 24 allowing arbitrarily large angles. Using the following custom format (Excel, OOo and LibreOffice will have equivalents but I don't have a copy to hand to test) will render them with the correct symbols as well. You can format numbers as time to get Excel (and probably OOo and LibreOffice) to display and calculate values that as you need with the correct divisions, bases, etc. There might be plugins around that help with this, but instead I'd like to offer a little work-around: Out of the box Excel has no support for what you are asking.
