format of each mode is like the following. maximum: always range mode e.g., 2012.03.04-2012.03.04 2023.04.05-2023.05.06 full (default): range mode is used only when beg and end is different e.g., 2012.03.04 2023.04.05-2023.05.06 compact: range mode remove duplicating information e.g., 2023.04.05-05.06 2023.04.?? minimum: (information loss can occur depending on dateformat) remove NA and duplicating info e.g., 2023.04-05 dateformat can use the following special characters. (percent)Yj(at): NOT WORKING (percent)YJ(at): NOT WORKING (percent)Y(at): YYYY年 (percent)y(at): YY年 (percent)M(at): MM月 (percent)m(at): M月 (percent)D(at): DD日 (percent)d(at): D日 (percent)Y: YYYY (percent)y: YY (percent)M: MM (percent)m: M (percent)D: DD (percent)d: D
