To determine how Yah calculates a day we only need to look at Creation. Each time it starts with darkness “it was evening and it was day”. But let us take note of the following verses:
13 And there came to be evening and there came to be morning, the third day.
5 ‘In the first new moon, on the fourteenth day of the new moon, between the evenings, is the Pĕsaḥ to יהוה.
A day is therefore determined from sunset to sunset. I day according to Scripture is therefore between the evenings from sunset to sunset. This is the easier part to calculating the calendar and therefore commonly accepted especially among those who accept Yeshua as Messiah and obey the Torah.
Remember that everything in the Scripture is cyclical. You will see the same pattern throughout Scripture.
- Evening then Day
- Sin then Salvation
- Tribulation then Overcoming
Darkness represents sin. Light represents righteousness. There was darkness before light just as there is sin before righteousness. It is a pattern.
Next we will tackle a more tricky part to the calendar: the month.
Until next time.
