Yahweh's day is only 12 hours long, not 24 hours like Satan's day.

John 11:9
Jesus answered, Are there not twelve hours in the day? If any man walk in the day, he stumbleth not, because he seeth the light of this world.

The remaining 12 hour period is called "night". We can see this in the length of time that Jesus fasted. In time reckoned by Satan it would have been 40 days, but in Yahweh's time it was 40 days PLUS 40 nights.

Matthew 4:1-2
Then was Jesus led up of the Spirit into the wilderness to be tempted of the devil. And when he had fasted forty days and forty nights, he was afterward an hungred.

And, again in the time that Jonah was in the whale and Christ in the tomb:

Matthew 12:40
For as Jonas was three days and three nights in the whale's belly; so shall the Son of man be three days and three nights in the heart of the earth.

Genesis 1:5
And Yahweh called the light Day, and the darkness he called Night. And the evening and the morning [dawn to dusk] were the first day.

Note - the darkness (night) doesn't count as part of Yahweh's day. Satan has a day that consists of a day and a night. That is impossible both grammatically and logically.

By this we know that Yahweh's day starts at dawn (sunrise) and ends at evening (sunset, dusk).

Instead of the names of pagan deities, Yahweh simply numbered His days - 1,2,3,4,5,6,7

Following, are a few more texts demonstrating a day during the time of Christ. At the eleventh hour, the men had stood idle "all day". When the day began to wear away (finish) it was time to find lodging. Cry day and night. In the day He was teaching and in the night He went to the mount of Olives.

Matt 20:6, Luke 9:12, Luke 18:7, Luke 21:37, Luke 22:66
