I thought I could start with sharing some culture things (that is how I grew up to do it, that means a small catholic village in Swabia (southe west Germany)). You probably all figured that I do not do Halloween simply because it does not exist here. And even though there is the 31st of October which is Reformation Day for the Protestants and there is Allerheiligen - All Saints' Day on 1st of November.
More personal is Allerseelen - All Souls' Day on the 2nd of November, the day we remember the dead, by visiting the cemetary and lightening candles. I won't be home this year - bu I might simply light a candle in the window.
