Common years have 365 days; leap years 366. Divisible by 4 is a leap year unless divisible by 100 but not 400. 2100 is common; 2000 was leap. The list below is that rule, not an omen table. Leap-day birthdays are often celebrated on 28 February or 1 March by local custom.
East Asian lunisolar calendars insert a leap month to track moons and solar terms. Talk that “the spirit is away” or that reburials are easier then bundles with son-eomneun-nal customs. We do not republish a paid lunar almanac day-by-day.
Some families avoid leap-year weddings (uneven pair, long year, ancestors resting). Others treat a leap month as auspicious. Marriage and infant health sit in relationships, medicine, and law — not a calendar stamp. If the venue is booked, superstition is a weak reason to break the contract.
Headlines about leap-year crashes or divorces need sample and definition checks. An extra day can add extra events. 29 February in novels is a plot device. Superpowers for leap-day births are fiction.
