Mr Holland (50) was last seen at his home in White Road at around 11am that day.
There have been several possible sightings of Mr Holland since he left home but his family have not seen or heard from him since.
Officers have followed up every sighting but these sightings have not yet led to any positive information regarding the whereabouts of Mr Holland.
His disappearance is completely out of character.
Mr Holland is around six feet tall, of medium build, with a shaved head. He was last seen wearing a grey top and shorts.
Extensive searches have been carried out by officers using the force helicopter and dogs. Supporters who attended the Chesterfield v Mansfield football match on Saturday were given leaflets and message was broadcast to the crowd.
The national charity Missing is also involved in the efforts to find Mr Holland.
Anyone who sees Mr Holland should ring the police on 101.
