Mary arrived at the tomb at about sunrise, the tomb was empty, and no guards around and Jesus was thought to be a gardener, my question, did Jesus arise before sunup, was the stone rolled away and was it dark when the guards went to report?

Yes. It is helpful to mention that the Gospel accounts place the resurrection on “the first day of the week,” after the Sabbath had ended, and in biblical reckoning the day began after sundown, not at midnight. So the first day of the week began after sunset.

This means Jesus could have risen at any time after Saturday sunset and before the women arrived at the tomb early Sunday morning.

John tells us that Mary Magdalene came to the tomb “early, while it was still dark” and found that the stone had already been removed (John 20:1). Mark says the women came “at the rising of the sun” (Mark 16:2). These statements fit together if the women began their journey while it was still dark and arrived as dawn was breaking.

Matthew also tells us that an angel descended, there was a great earthquake, and the stone was rolled away (Matthew 28:2–4). The guards were terrified and later went into the city to report what had happened (Matthew 28:11).

Scripture does not tell us the exact hour Jesus rose, nor does it specifically say whether it was still dark when the guards went to report. What we can say with certainty is that Jesus had already risen before the women arrived at the tomb around dawn.

So the resurrection may have taken place sometime during the night after Saturday sunset. The Bible simply does not give enough information to narrow it down further.
