Date Weekday Calculatorについて
Select a month, day, and target weekday, then choose a start and end year. The calculator scans each year in the range and lists every match as a full formatted date. February 29 is supported: non-leap years are skipped automatically. Invalid dates (such as April 31) and invalid year ranges show clear error messages.
