劳动节期间美国商业运营情况：政府关闭，零售业照常营业

美国劳动节是每年9月第一个周一的法定假日1。这一假期的起源可追溯至1882年9月5日，当时纽约举行了首次劳动节庆祝活动，约10,000名工人参加了游行1。1894年，美国总统格罗弗·克利夫兰签署国会法案，将9月第一个周一正式确立为法定假日1。

劳动节期间，政府办公室、邮局、法院、学校、美国股市和银行均停止运营1。大多数主要全国零售商和杂货店照常营业，许多企业推出促销活动吸引消费者；仅有Costco在劳动节关闭1。

今年劳动节假期的出行成本显著上升。根据AAA数据，国内航班价格较去年上涨近20%，酒店价格也随之上升1。汽油平均价格为每加仑不足4.10美元，较去年同期上升90美分1。邮轮价格较去年下降约4%1。

Labor Day, observed on the first Monday of September, is a federal holiday in the United States with roots tracing back to the late 19th century labor movement 1. The first Labor Day celebration took place on September 5, 1882, in New York, drawing approximately 10,000 workers to a parade 1. In 1894, President Grover Cleveland signed a congressional act establishing the first Monday in September as an official federal holiday 1.

This year, the holiday will see most major retail chains and grocery stores remain open for business, with many offering promotional deals to attract consumers 1. However, government offices, post offices, courts, and schools will be closed, along with the stock market and banks 1. Costco is an exception among major retailers, choosing to close on Labor Day 1.

Travel costs during the holiday period have increased significantly compared to last year 1. Domestic airline ticket prices have risen nearly 20 percent, while hotel rates have also climbed 1. Gas prices average just under $4.10 per gallon, up 90 cents from the same period last year, according to AAA data 1. In contrast, cruise prices have declined approximately 4 percent year-over-year 1.
