So dear brother, please make it simpler for those who use current western calender. This means that Friday evening to Saturday evening is always Shabbat/Sabbath.
Blessings in YHVH/YAHshua.
Quoting: FHL(C) nli 33966782 yes you can use the link and put in your zone and test it for yourself.ADAR IS THE LAST MONTH OF THE YEAR WHICH IS FEBRUARY-MARCH.
So put in the month of march and see which day the sun rise and the sunset are equal.
When you get that day you have established the day before the vernal equinox.
The day after the sunset is the new year
the proof her is that the day before the new year always falls on the shabbat and the new year is always the firt day of the week.
This is contnuous through out the 52 week cycle and counting from the ist day it is evident that the seventh day cycle is correct..
seven is completion and that is why the year ends on the shabbat
God satarted work creation on the first day! that is why the year starts on the first day
So this is vital proof of our creator and that we should stay on his clock
