On August 8th, 2028, a record number of Japanese couples lined up to register their marriages, capitalizing on what is considered an auspicious date in Japan. The combination of the number 8, valued for its symmetrical shape symbolizing balance, and the Reiwa period's eigth year made this date highly sought after for weddings. Registration offices across the country saw unusually long queues as couples sought to embark their journey in matrimony under the umbrella of this good fortune.

In Japan, certain days and numbers are believed to bring luck or misfortune based on their readings in kanji. The number 8 (hachi in Japanese), resembling infinity (∞), signifies prosperity and happiness. The Reiwa era, a new period in the Japanese calendar which began in 2019, is seen as a fresh start, making the date even more special.

Unlike in Japan, there isn't a widespread belief about auspicious dates in the US or EU. While individual cultures or subcultures have various superstitions, these are not as widespread or homogenous as in Japan. However, historically significant dates or easy-to-remember dates are sometimes favored.
