NAME Acme::CPANModules::CalculatingDayOfWeek - List of modules to calculate day of week VERSION This document describes version 0.002 of Acme::CPANModules::CalculatingDayOfWeek (from Perl distribution Acme-CPANModules-CalculatingDayOfWeek), released on 2023-08-06. SYNOPSIS To run benchmark with default option: % bencher --cpanmodules-module CalculatingDayOfWeek To run module startup overhead benchmark: % bencher --module-startup --cpanmodules-module CalculatingDayOfWeek For more options (dump scenario, list/include/exclude/add participants, list/include/exclude/add datasets, etc), see bencher or run "bencher --help". ACME::CPANMODULES ENTRIES Date::DayOfWeek Author: RBOW Both Date::DayOfWeek and Time::DayOfWeek are lightweight modules. Time::DayOfWeek Author: PIP 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 Author: DROLSKY Compared to Date::DayOfWeek and Time::DayOfWeek, DateTime is a behemoth. But it provides a bunch of other functionalities as well. Date::Calc 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 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. BENCHMARKED MODULES Version numbers shown below are the versions used when running the sample benchmark.

FAQ What is an Acme::CPANModules::* module? An Acme::CPANModules::* module, like this module, contains just a list of module names that share a common characteristics. It is a way to categorize modules and document CPAN. See Acme::CPANModules for more details. What are ways to use this Acme::CPANModules module? Aside from reading this Acme::CPANModules module's POD documentation, you can install all the listed modules (entries) using cpanm-cpanmodules script (from App::cpanm::cpanmodules distribution): % cpanm-cpanmodules -n CalculatingDayOfWeek Alternatively you can use the cpanmodules CLI (from App::cpanmodules distribution): % cpanmodules ls-entries CalculatingDayOfWeek | cpanm -n or Acme::CM::Get: % perl -MAcme::CM::Get=CalculatingDayOfWeek -E'say $_->{module} for @{ $LIST->{entries} }' | cpanm -n or directly: % perl -MAcme::CPANModules::CalculatingDayOfWeek -E'say $_->{module} for @{ $Acme::CPANModules::CalculatingDayOfWeek::LIST->{entries} }' | cpanm -n This Acme::CPANModules module contains benchmark instructions. You can run a benchmark for some/all the modules listed in this Acme::CPANModules module using the bencher CLI (from Bencher distribution): % bencher --cpanmodules-module CalculatingDayOfWeek This Acme::CPANModules module also helps lcpan produce a more meaningful result for "lcpan related-mods" command when it comes to finding related modules for the modules listed in this Acme::CPANModules module. See App::lcpan::Cmd::related_mods for more details on how "related modules" are found. HOMEPAGE Please visit the project's homepage at . SOURCE Source repository is at .

Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via: % prove -l If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins.
