    auto mdl {February/last}; // Last day of a February
    auto ymdl {year(2020)/mdl};
    std::cout << (year_month_day{ymdl} == 
                  year_month_day{February/29/2020}) << ' ';
    // Last day of the next month, in 2020
    mdl = {(mdl.month() + months(1))/last};
    ymdl = {year(2020)/mdl}; 
    std::cout << (year_month_day{ymdl} == 
                  year_month_day{March/31/2020}) << '\n';
