gem 'working_hours'
Usage
require 'working_hours'
# Move forward
1.working.day.from_now
2.working.hours.from_now
15.working.minutes.from_now
# Move backward
1.working.day.ago
2.working.hours.ago
15.working.minutes.ago
# Start from custom Date or Time
Date.new(2014, 12, 31) + 8.working.days # => Mon, 12 Jan 2015
Time.utc(2014, 8, 4, 8, 32) - 4.working.hours # => 2014-08-01 13:00:00
# Compute working days between two dates
friday = Date.new(2014, 10, 17)
monday = Date.new(2014, 10, 20)
friday.working_days_until(monday) # => 1
# Time is considered at end of day, so:
# - friday to saturday = 0 working days
# - sunday to monday = 1 working days
# Compute working duration (in seconds) between two times
from = Time.utc(2014, 8, 3, 8, 32) # sunday 8:32am
to = Time.utc(2014, 8, 4, 10, 32) # monday 10:32am
from.working_time_until(to) # => 5520 (1.hour + 32.minutes)
# Know if a day is worked
Date.new(2014, 12, 28).working_day? # => false
# Know if a time is worked
Time.utc(2014, 8, 4, 7, 16).in_working_hours? # => false
# Advance to next working time
WorkingHours.advance_to_working_time(Time.utc(2014, 8, 4, 7, 16)) # => Mon, 04 Aug 2014 09:00:00 UTC +00:00
# Advance to next closing time
WorkingHours.advance_to_closing_time(Time.utc(2014, 8, 4, 7, 16)) # => Mon, 04 Aug 2014 17:00:00 UTC +00:00
WorkingHours.advance_to_closing_time(Time.utc(2014, 8, 4, 10, 16)) # => Mon, 04 Aug 2014 17:00:00 UTC +00:00
WorkingHours.advance_to_closing_time(Time.utc(2014, 8, 4, 18, 16)) # => Tue, 05 Aug 2014 17:00:00 UTC +00:00
# Next working time
sunday = Time.utc(2014, 8, 3)
monday = WorkingHours.next_working_time(sunday) # => Mon, 04 Aug 2014 09:00:00 UTC +00:00
tuesday = WorkingHours.next_working_time(monday) # => Tue, 05 Aug 2014 09:00:00 UTC +00:00
# Return to previous working time
WorkingHours.return_to_working_time(Time.utc(2014, 8, 4, 7, 16)) # => Fri, 01 Aug 2014 17:00:00 UTC +00:00
Configuration
The working hours configuration is thread safe and consists of a hash defining working periods for each day, a time zone and a list of days off. You can set it once, for example in a initializer for rails:
# Configure working hours
WorkingHours::Config.working_hours = {
:tue => {'09:00' => '12:00', '13:00' => '17:00'},
:wed => {'09:00' => '12:00', '13:00' => '17:00'},
:thu => {'09:00' => '12:00', '13:00' => '17:00'},
:fri => {'09:00' => '12:00', '13:00' => '17:05:30'},
:sat => {'19:00' => '24:00'}
}
# Configure timezone (uses activesupport, defaults to UTC)
WorkingHours::Config.time_zone = 'Paris'
# Configure holidays
WorkingHours::Config.holidays = [Date.new(2014, 12, 31)]
Or you can set it for the duration of a block with the with_config
method, this is particularly useful with around_filter
:
WorkingHours::Config.with_config(working_hours: {mon:{'09:00' => '18:00'}}, holidays: [], time_zone: 'Paris') do
# Intense calculations
end
with_config
uses keyword arguments, you can pass all or some of the supported arguments :
working_hours
holidays
time_zone
Holiday hours
Sometimes you need to configure different working hours as a one-off, e.g. the working day might end earlier on Christmas Eve.
You can configure this with the holiday_hours
option, either as an override on the existing working hours, or as a set of hours that are being worked on a holiday day.
If any hours are set for a calendar day in holiday_hours
, then the working_hours
for that day will be ignored, and only the entries in holiday_hours
taken into consideration.
# Configure holiday hours
WorkingHours::Config.holiday_hours = {Date.new(2020, 12, 24) => {'09:00' => '12:00', '13:00' => '15:00'}}
Handling errors
If the configuration is erroneous, an WorkingHours::InvalidConfiguration
exception will be raised containing the appropriate error message.
You can also access the error code in case you want to implement custom behavior or changing one specific message, e.g:
rescue WorkingHours::InvalidConfiguration => e
if e.error_code == :empty
raise StandardError.new "Config is required"
end
raise e
end
No core extensions / monkey patching
Core extensions (monkey patching to add methods on Time, Date, Numbers, etc.) are handy but not appreciated by everyone. WorkingHours can also be used without any monkey patching:
require 'working_hours/module'
# Move forward
WorkingHours::Duration.new(1, :days).from_now
WorkingHours::Duration.new(2, :hours).from_now
WorkingHours::Duration.new(15, :minutes).from_now
# Move backward
WorkingHours::Duration.new(1, :days).ago
WorkingHours::Duration.new(2, :hours).ago
WorkingHours::Duration.new(15, :minutes).ago
# Start from custom Date or Time
WorkingHours::Duration.new(8, :days).since(Date.new(2014, 12, 31)) # => Mon, 12 Jan 2015
WorkingHours::Duration.new(4, :hours).until(Time.utc(2014, 8, 4, 8, 32)) # => 2014-08-01 13:00:00
# Compute working days between two dates
friday = Date.new(2014, 10, 17)
monday = Date.new(2014, 10, 20)
WorkingHours.working_days_between(friday, monday) # => 1
# Time is considered at end of day, so:
# - friday to saturday = 0 working days
# - sunday to monday = 1 working days
# Compute working duration (in seconds) between two times
from = Time.utc(2014, 8, 3, 8, 32) # sunday 8:32am
to = Time.utc(2014, 8, 4, 10, 32) # monday 10:32am
WorkingHours.working_time_between(from, to) # => 5520 (1.hour + 32.minutes)
# Know if a day is worked
WorkingHours.working_day?(Date.new(2014, 12, 28)) # => false
# Know if a time is worked
WorkingHours.in_working_hours?(Time.utc(2014, 8, 4, 7, 16)) # => false
Use in your class/module
If you want to use working hours only inside a specific class or module, you can include its computation methods like this:
require 'working_hours/module'
class Order
include WorkingHours
def shipping_date_estimate
Duration.new(2, :days).since(payment_received_at)
end
def payment_delay
working_days_between(created_at, payment_received_at)
end
end
Timezones
This gem uses a simple but efficient approach in dealing with timezones. When you define your working hours you have to choose a timezone associated with it (in the config example, the working hours are in Paris time). Then, any time used in calculation will be converted to this timezone first, so you don't have to worry if your times are local or UTC as long as they are correct :)
Alternatives
There is a gem called business_time already available to do this kind of computation and it was of great help to us. But we decided to start another one because business_time is suffering from a few bugs and inconsistencies. It also lacks essential features to us (like working minutes computation).
Another gem called biz was released after working_hours to bring some alternative.
