# Help with ZODIAC Rotation

Hi @ll, i am experimenting on a Zodiac rotation but can´t get it to work with the right days…

I used the formula posted from Mellin:

(((#DM# + (clamp((#Dd# - 19),0,1))) / 12) * 360)

http://community.facer.io/t/help-to-create-a-once-a-month-rotation-on-a-specific-day/14033/6

The problem is, that it differs up to 3 days from the real dates:

For example: Lion is dated from 23. July to 22.August — in the preview it changes from cancer to lion on 20. July.

Anybody an idea?

I know that it can differ 1 day due to leap-years but 3 days???

Help very much appreciated!

Greetings, GAUSS.

Never tried Zodiac rotation but if it is consistently off by 3 days, could you just minus by 3? I am probably completely off though. I’ll have to try this.

No, i am afraid it´s not consistently off by 3 days … That would be to easy, lol…

Haha I figured that would be too easy. Always gotta try the obvious just to rule it out lol.

Absolutly right That´s my first method as well…

Just was taking a look and that rotational formula switches every month on the 20th unless you change the 19 to a different number.

I had worked out a zodiac formula in Excel ages ago. I can try to locate it for you but not entirely sure if the functions I used will translate to Creator.
Rather than a rotational scheme, would a formula to select the date to change the sign work for you?

Well, i could use a transparency formula instead of rotation - it´s an alternative …

Thanks for your participation!

I suspect it relates to sign (negative vs positive) …

Give me a couple of days. I will write a formula that returns 0…11 .

based on:

WESTERN ASTROLOGY STAR SIGN

Dec. 22 - Jan. 19 - Capricorn
Jan. 20 - Feb. 17 - Aquarius
Feb. 18 - Mar. 19 - Pisces
March 20 - April 19 - Aries
April 20 - May 19 - Taurus
May 20 - June 20 - Gemini
June 21 - July 21 - Cancer
July 22 - Aug. 22 - Leo
Aug 23 - Sept. 21 - Virgo
Sept. 22 - Oct. 22 - Libra
Oct. 23 - Nov. 21 - Scorpio
Nov. 22 - Dec. 21 - Sagittarius

That would be great!
Thanks a lot!

Wow! Wasn‘t online a while… Great work, i will try out tomorrow!

Thanks a lot for your effort!

Greetings, GAUSS.

Great!

I had to change your formula a little bit to rotate clockwise (i made a different template) and correct a few datas because i have an other chart:

http://www.astrovision.de/Sternzeichen-Tabelle.php

Widder 21.03. - 20.04
Stier 21.04. - 20.05
Zwillinge 21.05. - 21.06
Krebs 22.06. - 22.07
Löwe 23.07. - 23.08
Jungfrau 24.08. - 23.09
Waage 24.09. - 23.10
Skorpion 24.10. - 22.11
Schütze 23.11. - 21.12
Steinbock 22.12. - 20.01
Wassermann 21.01. - 19.02
Fische 20.02. - 20.03

This is what my modified formula looks like now:

(-(\$#DD#<=20||#DD#>=356?0:\$\$#DD#>=21&&#DD#<=50?30:\$\$#DD#>=51&&#DD#<=79?60:\$\$#DD#>=80&&#DD#<=109?90:\$\$#DD#>=110&&#DD#<=139?120:\$\$#DD#>=140&&#DD#<=171?150:\$\$#DD#>=172&&#DD#<=202?180:\$\$#DD#>=203&&#DD#<=234?210:\$\$#DD#>=235&&#DD#<=265?240:\$\$#DD#>=266&&#DD#<=295?270:\$\$#DD#>=296&&#DD#<=326?300:\$\$#DD#>=327&&#DD#<=355?330:\$)+90)

It was really a great help for me. Thank you!

Wow @andrew.dowden Nice work!

@GAUSS , cant wait to see the final results! Looks good so far.

Yes, I also found several charts … all slightly different.

I might see if I can find an astronomy (science) based reference, rather than astrology (multiple conventions).

There is US ‘The Farmers Almanac’, which might be concidered definitive.

It‘s strange how much different charts are on the web. I searched a lot since i was sure that the one i took seems to be the casual one associated to the date of birth. I know, that they can differ in leap years.
