'Mid day' in the Bible

But an angel of the Lord said to Philip, “Get up and go south to the road that runs from Jerusalem down to Gaza.” (This is a desert road).

On the next day, while these men were on their way, just as they were nearing the town, Peter went up on the housetop about mid-day to pray.

And it came to pass, as I was journeying and drawing near to Damascus, that, about mid-day, there suddenly shone out of heaven a great light round about me.

On which accounts as I was going to Damascus with authority and commission from the chief priests---at mid-day,

At midday, O king, I saw in the way a light from heaven, above the brightness of the sun, shining round about me and them which journeyed with me.
