Peter's Xmas 2020 Newsletter mention of 12th Night set me off on the many times I have crossed swords on the subject of Christmas, both when it starts and when it ends, and will begin at the end.
As a child there was no question as to when the 'trimmings' (and in Birmingham decorations were known by no other name) came down. That, as Peter reminds for his own childhood, was 6th January. Both grandmothers brought up their respective offspring to honour this date so the trimmings came down on 6th January, referred to as Twelfth Night.
Then I married and moved to rural south Northamptonshire where the majority view favoured the 5th January. My mother-in-law insisted that this was the day for removing decorations (and yes decorations now held sway) - so 5th January it was. As it was also traditional in the area for the work to be done by the ladies (and men were mostly at work anyway) I went along with the status quo. Besides - as someone with a mathematical bent - if counting began with Christmas Day (which seemed to me logical) - then the 5th January won me over then as now.
But my views on when decorations should go up have always been strong and voiced many times previously, and with a second wife who shares my views there is no household argument on the subject. Besides she takes little part in the putting up or taking down. I never 'deck the halls' earlier than the week before Christmas, but like to await the 5th January before taking them down with, perhaps, a tiny bit of guilt for not waiting until the next day!
My sister in Australia (and coincidently my grand daughter-in-law in the UK) insist decorations go up on the 1st December, with the latter posting photos on Facebook to prove it. I believe in both cases they are taken down on the 1st or 2nd January depending on whether New Years day (a Bank holiday) is spent in other ways. My UK sister also likes her Tree on show (artificial with built in lights) the first week of January, and thinks the day after New Years day is the right time to return the Tree to its box and the loft. (So twelfth night plays no part).
As for cousins, including those still Birmingham based, there appears to be no fixed time for putting up the 'trimmings' (I am so pleased they still refer to them as that) but all far earlier than cousin Bobby who they all know doesn't even like mention of the 'C' word before the second week of December. As for the taking down, I could not find two the same and few even wait until the 5th January. "Now't so funny as folk" springs to mind and I wonder how many others have set times for the putting up and taking down of Christmas decorations.
