PersianCalender

A Ruby gem that provides Persian (Jalali) calendar functionality for Ruby and Rails applications. This gem allows you to convert between Gregorian and Persian dates, format Persian dates, and use Persian dates in Rails applications.

Install the gem and add to the application's Gemfile by executing:

bundle add persian_calender

Or add it to your Gemfile manually:

gem 'persian_calender'

If bundler is not being used to manage dependencies, install the gem by executing:

gem install persian_calender

# Create a new Persian date
persian_date = PersianCalender.new(1402, 12, 15)

# Convert from Gregorian to Persian
persian_date = PersianCalender.from_gregorian(2024, 3, 5)

# Convert from Persian to Gregorian
gregorian_date = persian_date.to_gregorian
# => { year: 2024, month: 3, day: 5 }

# Format a Persian date
persian_date.to_s                 # => "1402-12-15"
persian_date.to_s(format: :short) # => "1402/12/15"
persian_date.to_s(format: :long)  # => "15 اسفند 1402"
persian_date.to_s(format: :long_en) # => "15 Esfand 1402"

# Get month name
persian_date.month_name          # => "اسفند"
persian_date.month_name(english: true) # => "Esfand"

# Add days to a Persian date
new_date = persian_date.add_days(10)

class Event < ApplicationRecord
  # Assuming you have a 'date' column in your database
  persian_date :persian_date
end

# Usage:
event = Event.new
event.persian_date = "1402/12/15" # Sets the date field with the Gregorian equivalent
event.persian_date # Returns a PersianCalender object

<%= persian_date(@event.date) %>
<%= persian_date(@event.date, format: :long) %>

<%= form_for @event do |f| %>
  <%= persian_date_select f, :persian_date %>
<% end %>
