Seder is one of those words that gets casually thrown around a lot. The word seder means “order,” and when you think of a seder, you usually think of Passover. At Passover, the seder is an entire ritual of readings and blessings that take place before, during and after the meal.
The Passover seder can vary greatly between families but there are some elements that are the same and it is really and truly an “event.” Everyone gets together and focuses on remembrance and celebration.
If someone speaks casually about a seder, they are probably thinking about Passover. However, there are seders associated with other holidays and a Shabbat seder for Friday night.
