Reason Scots must clean today and then put feet up until January 2

dailyrecord.co.uk:

As Scots prepare to bring in the bells tonight, they might want to get their cleaning and washing up to date before the clock strikes midnight.

That's because tradition states that tomorrow (New Year's Day) there should be no cleaning done unless you want to bring bad luck to your home.

For many Scots, Hogmanay is when they take on 'redding the house'. This is the act of cleaning your home ahead of the new year, since it was thought to be bad luck to start a year with a dirty house.

And it's a practice that still holds today. This thorough house cleaning, from top to bottom, included the removal of ashes from the fireplace and had to be complete before midnight.
