=head1 NAME
Acme::CPANModules::CalculatingDayOfWeek - List of modules to calculate day of week
=head1 VERSION
This document describes version 0.002 of Acme::CPANModules::CalculatingDayOfWeek (from Perl distribution Acme-CPANModules-CalculatingDayOfWeek), released on 2023-08-06.
=head1 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 L<bencher> or run C<bencher --help>.
=head1 ACME::CPANMODULES ENTRIES
=over
=item L<Date::DayOfWeek>
Author: L<RBOW|https://metacpan.org/author/RBOW>
Both L<Date::DayOfWeek> and L<Time::DayOfWeek> are lightweight modules.
=item L<Time::DayOfWeek>
Author: L<PIP|https://metacpan.org/author/PIP>
Both L<Date::DayOfWeek> and L<Time::DayOfWeek> are lightweight modules.
This module offers cryptic and confusing function names: C<DoW> returns 0-6,
C<Dow> returns 3-letter abbrev.
=item L<DateTime>
Author: L<DROLSKY|https://metacpan.org/author/DROLSKY>
Compared to L<Date::DayOfWeek> and L<Time::DayOfWeek>, L<DateTime> is a
behemoth. But it provides a bunch of other functionalities as well.
=item L<Date::Calc>
Author: L<STBEY|https://metacpan.org/author/STBEY>
L<Date::Calc> is a nice compromise when you want something that is more
lightweight and does not need to be as accurate as L<DateTime>.
=item L<Time::Moment>
Author: L<CHANSEN|https://metacpan.org/author/CHANSEN>
L<Time::Moment> is also a nice alternative to L<DateTime>. Although it's not
as featureful as DateTime, it is significantly more lightweight. Compared to
L<Date::Calc>, Time::Moment's API is closer to DateTime's. Being an XS module,
it's also faster.

=head1 FAQ
=head2 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 L<Acme::CPANModules> for more details.
=head2 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 L<cpanm-cpanmodules> script (from
L<App::cpanm::cpanmodules> distribution):
% cpanm-cpanmodules -n CalculatingDayOfWeek
Alternatively you can use the L<cpanmodules> CLI (from L<App::cpanmodules>
distribution):
% cpanmodules ls-entries CalculatingDayOfWeek | cpanm -n
or L<Acme::CM::Get>:
% perl -MAcme::CM::Get=CalculatingDayOfWeek -E'say $_->{module} for @{ $LIST->{entries} }' | cpanm -n
