Thanks, good spot
Well I've learned something new - the US date is the 2nd Sunday in May whilst the UK date is the 4th Sunday of lent. We also (officially) call it "Mothering Sunday", Mother's Day being the US title.
Anyway, all the dates are changed and when I get a chance I'll check the Father's day dates
Any of the others incorrect? Apparently D-Day is 6 June each year, although we don't seem to celebrate it here. Any I should be adding (and can you get me the dates)?
