Remark

However, the above program includes some problems for calculating the future
old-calendar datas. So, I have done some adjustments.

Installation

Add this line to your application's Gemfile:

gem 'mk_calendar'

And then execute:

$ bundle

Or install it yourself as:

$ gem install mk_calendar

Usage

Instantiation

require 'mk_calendar'

obj = MkCalendar.new

# Otherwise
obj = MkCalendar.new("20160608")

Calculation

p o.year, o.month, o.day, o.jd, o.jd_jst
p o.holiday
p o.sekki_24
p o.zassetsu
p o.yobi
p o.kanshi
p o.sekku
p o.lambda
p o.alpha
p o.moonage
p o.oc  # <= [year, leap_flag, month, day]

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment. Run bundle exec mk_calendar to use the gem in this directory, ignoring other installed copies of this gem.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
