# The Date Helper primarily creates select/option tags for different kinds of dates and date elements. All of the select-type methods
# share a number of common options that are as follows:
#
# * :prefix - overwrites the default prefix of "date" used for the select names. So specifying "birthday" would give
# birthday[month] instead of date[month] if passed to the select_month method.
# * :include_blank - set to true if it should be possible to set an empty date.
# * :discard_type - set to true if you want to discard the type part of the select name. If set to true, the select_month
# method would use simply "date" (which can be overwritten using :prefix) instead of "date[month]".

# Reports the approximate distance in time between two Time or Date objects or integers as seconds.
# Set include_seconds to true if you want more detailed approximations when distance < 1 min, 29 secs
# Distances are reported base on the following table:
#
# 0 <-> 29 secs # => less than a minute
# 30 secs <-> 1 min, 29 secs # => 1 minute
# 1 min, 30 secs <-> 44 mins, 29 secs # => [2..44] minutes
# 44 mins, 30 secs <-> 89 mins, 29 secs # => about 1 hour
# 89 mins, 29 secs <-> 23 hrs, 59 mins, 29 secs # => about [2..24] hours
# 23 hrs, 59 mins, 29 secs <-> 47 hrs, 59 mins, 29 secs # => 1 day
# 47 hrs, 59 mins, 29 secs <-> 29 days, 23 hrs, 59 mins, 29 secs # => [2..29] days
# 29 days, 23 hrs, 59 mins, 30 secs <-> 59 days, 23 hrs, 59 mins, 29 secs # => about 1 month
# 59 days, 23 hrs, 59 mins, 30 secs <-> 1 yr minus 31 secs # => [2..12] months
# 1 yr minus 30 secs <-> 2 yrs minus 31 secs # => about 1 year
# 2 yrs minus 30 secs <-> max time or date # => over [2..X] years
#
# With include_seconds = true and the difference < 1 minute 29 seconds
# 0-4 secs # => less than 5 seconds
# 5-9 secs # => less than 10 seconds
# 10-19 secs # => less than 20 seconds
# 20-39 secs # => half a minute
# 40-59 secs # => less than a minute
# 60-89 secs # => 1 minute

# Returns a set of select tags (one for year, month, and day) pre-selected for accessing a specified date-based attribute (identified by
# +method+) on an object assigned to the template (identified by +object+). It's possible to tailor the selects through the +options+ hash,
# which accepts all the keys that each of the individual select builders do (like :use_month_numbers for select_month) as well as a range of
# discard options. The discard options are :discard_year, :discard_month and :discard_day. Set to true, they'll
# drop the respective select. Discarding the month select will also automatically discard the day select. It's also possible to explicitly
# set the order of the tags using the :order option with an array of symbols :year, :month and :day in
# the desired order. Symbols may be omitted and the respective select is not included.
#
# Pass the :default option to set the default date. Use a Time object or a Hash of :year, :month, :day, :hour, :minute, and :second.
#
# Passing :disabled => true as part of the +options+ will make elements inaccessible for change.
#
# NOTE: Discarded selects will default to 1. So if no month select is available, January will be assumed.
