INCLUDED MODULES * Date::DayOfWeek Both Date::DayOfWeek and Time::DayOfWeek are lightweight modules. * Time::DayOfWeek Both Date::DayOfWeek and Time::DayOfWeek are lightweight modules. This module offers cryptic and confusing function names: "DoW" returns 0-6, "Dow" returns 3-letter abbrev. * DateTime Compared to Date::DayOfWeek and Time::DayOfWeek, DateTime is a behemoth. But it provides a bunch of other functionalities as well. * Date::Calc 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 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.
