UK Holidays

Main article: Remind

These are some standard UK holidays in remind format, add them as an include in your .reminders file.

Some notes:

• These are the England & Wales bank holidays, feel free to add the Scotland and Ireland ones.
• The Bank Holiday date definitions are taken from the Bank Holidays wikipedia page.
• The May, Spring and Summer bank holidays, and the Boxing day bank holiday aren't OMITs because they use weekday date specifiers, which generate an error ("Unknown token: `Mon' (OMIT)"). If anyone knows a way around this, please correct them.
• If anyone can think of a way to add a reminder for Remembrance Sunday—defined as the Sunday nearest (before or after) the 11th of November—please add it.
• Can anyone think of rules to accommodate Christmas Day or New Years Day falling on a Sat or Sun? Eg. 27th/28th December 2010. This is especially complex when Christmas Day is a Sat as Boxing Day becomes the following Mon and the Tue an additional Holiday.
