    Date::Calc
        Author: STBEY <https://metacpan.org/author/STBEY>

        Date::Calc is a nice compromise when you want something that is more
        lightweight and does not need to be as accurate as DateTime.

    Time::Moment
        Author: CHANSEN <https://metacpan.org/author/CHANSEN>

        Time::Moment is also a nice alternative to DateTime. Although it's
        not as featureful as DateTime, it is significantly more lightweight.
        Compared to Date::Calc, Time::Moment's API is closer to DateTime's.
        Being an XS module, it's also faster.
