In my home at New Year I never turn a calendar to show January until after midnight. I was taught from my Glasgow grandparents that it was bad luck to show the face of the calendar before the new year. Our tradition was to take down the old calendar on New Year's Eve and replace it with a new calendar, but to show the back blank page. When it was past midnight as a child I was allowed to turn all the calendars in the house around. I still carry this practise on today. In addition my family always thought it was bad luck to buy your own calendar, so we always purchase other family members one as a Christmas present.
