Strict parsing requires that the format and input match exactly, including delimiters. dayjs('1970-00-00', 'YYYY-MM-DD').isValid() // true dayjs('1970-00-00', 'YYYY-MM-DD', true).isValid() // false dayjs('1970-00-00', 'YYYY-MM-DD', 'es', true).isValid() // false · If you don't know the exact format of an input string, but know it could be one of many, you can use an array of formats.
