Here's some Hungarian customs and beliefs, which I think not necessarily specific for our folk, it's more of a Christian stuff, which also includes Western pre-Christian notions (I've no idea how much sipped into the traditions from the Hungarian pagan past). Also some of these are true only for certain regions of the country. This also doesn't mean these don't have analogies abroad.

During the week of these days working on the fields, or washing clothes, or whitewashing the walls were forbidden. But they had a day to hire servants (obviously this isn't a living tradition anymore).
They baked milk-loaves, sometimes given to beggars to pray for their dead.
Some cemeteries had belfries and the people of the village rung the bell all day. One people after another rung as many times as the number of dead they had. The people stood and waited to their turn and prayed.
They cleaned the graves and beautified them, brought flowers, so the dead will stay there.
The feeding of dead was also widespread, but was different everywhere. Examples are: placing bread, salt, and water onto the table for the night; adding one more plate for the dead during dinner; bringing bread to the grave and leaving it there; etc.
Lighting candles at home also help the dead to move about the house safely.
During the night between All Saint's Day and All Souls' Day the dead have their mass in the church. If a living person see them, he will die instantly.
