Describe a tradition in your country

The tradition I'd probably talk about is Lunar New Year, which in my part of the world is easily the most significant date on the calendar, more so than any Western-style New Year's Eve. It falls sometime between late January and mid-February, depending on the lunar calendar, so the exact date actually shifts a bit every year, which still occasionally catches people off guard with how early or late it lands. What people do, broadly, is spend the days beforehand cleaning the entire house from top to bottom — there's a belief that you're sweeping out the bad luck of the previous year — and then the whole extended family gathers, sometimes travelling considerable distances to do it, for a big meal on the eve itself, followed by several days of visiting relatives' houses in a fairly specific order, starting with the eldest. Children get small red envelopes with money in them, which is honestly the part everyone under about twelve cares most about. Why it matters, I think, goes beyond the food and the decorations, which are obviously part of the appeal — it's really one of the only times in the year when everyone stops working, without exception, and is expected to just be with family for several consecutive days. In a culture where people work fairly long hours the rest of the year, that enforced pause is arguably more valuable than the celebration itself, even if nobody quite puts it that way.
