Oak Apple Day
Oak Apple Day or Royal Oak Day was a formal public holiday celebrated in England on 29 May to commemorate the restoration of the English monarchy, in May 1660. In some parts of the country the day is still celebrated and has also been known as Shick Shack Day, Oak and Nettle Day or Arbor Tree Day.
In 1660, Parliament declared 29 May a public holiday:
- "Parliament had ordered the 29 of May, the King's birthday, to be for ever kept as a day of thanksgiving for our redemption from tyranny and the King's return to his Government, he entering London that day." 
The public holiday, Oak Apple Day, was formally abolished in 1859, but the date retains some significance in local or institutional customs. It is, for example, kept as Founder's Day in the Royal Hospital Chelsea (founded by Charles II in 1681).
Traditional celebrations to commemorate the event often entailed the wearing of oak apples (a type of plant gall, possibly known in some parts of the country as a shick-shack, but see the article on its etymology in the external links) or sprigs of oak leaves, in reference to the occasion after the Battle of Worcester in September 1651, when the future Charles II of England escaped the Roundhead army by hiding in an oak tree near Boscobel House. Anyone who failed to wear a sprig of oak risked being pelted with bird's eggs or thrashed with nettles.
These ceremonies, which have now largely died out, are perhaps continuations of pre-Christian nature worship. The Garland King who rides through the streets of Castleton, Derbyshire, at the head of a procession, completely disguised in a garland of flowers, which is later affixed to a pinnacle on the parish church tower, can have little connection with the Restoration, even though he dresses in Stuart costume. He is perhaps a kind of Jack in the Green and the custom may have transferred from May Day when such celebrations were permitted again after having been banned by the Puritans.
Events still take place at Upton-upon-Severn, Northampton, Aston on Clun in Shropshire, Marsh Gibbon in Buckinghamshire, Great Wishford in Wiltshire when villagers gather wood in Grovely Wood, and Membury in Devon. The day is generally marked by re-enactment activities at Moseley Old Hall, one of the houses where Charles II hid in 1651.
Oak Apple Day is also celebrated in the Cornish village of St Neot annually. The Vicar leads a procession through the village, he is followed by the Tower Captain holding the Oak bough. A large number of the villagers follow walking to the Church. A story of the history of the event is told and then the Vicar blesses the branch. The Tower Captain throws the old branch down from the top of the Tower and a new one is hauled to the top. Everyone is then invited to the Vicarage gardens and refreshments and a barbeque is eaten. Up to 12 noon villagers wear a sprig of "red" (new) oak and in the afternoon wear a sprig of "Boys Love" Artemisia Abrotanum, tradition dictates that the punishment for not doing this results in being stung by nettles.
