The stacks themselves are no more than thousands of years old, from (geologically speaking) very recent marine erosion. Significant changes to Old Harry Rock have been made within the last 100 years.
The rock itself (chalk) is Cretaceous so over 65 million years old.
The upland from which they are being eroded is of Tertiary age, so younger.
They are made of chalk, with some bands of flint.

Old harry was a stack. Old harry was an old man who drove his ships in. His wife every night stood on the end of the rock holding a lamp out so Old Harry wouldn't crash his boat. One night old harry went out in his boat and his wife was in the pub. Old Harry's wife was drunk and was walking out along the stacks and fell off and died. Along came old harry in his boat and because there was no lamp he crashed his boat in to a millions of pieces and he died to. So that is how Old Harry the stack got its name.
The Old Harry Rocks are part of a chalk band that is around 65 million years old. But the rock band has only been submerged by the sea in the last few thousand years. The current rocks known as Old Harry and his wife are a few centuries old, with Harry's original "wife" having collapsed in 1509. The 65Ma event was the KT Boundary, the end of the Cretaceous during which the chalk was formed. The subsequent uplift that formed the uplands from that Chalk was in the Tertiary, which followed the Cretaceous. The stacks themselves are no more than thousands of years old, as the Dorset coast retreated by marine erosion in the sea-level rise following the last Ice Age. The Old Harry rocks are simply stacks left by erosion of the chalk cliff in Purbeck, which extends under the sea all the way to the Needles on the Isle of Wight.
the rocks had eroded
The reason why OHR (Old Harry Rocks) are called so, is because they were named after a famous pirate, Harry Paye, known as "Old Harry." A different legend claims that Old Harry is a euphemism for the devil (Satan).
