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

      #
      # ==== Options
      # * <tt>:use_month_numbers</tt> - Set to true if you want to use month numbers rather than month names (e.g.
      #   "2" instead of "February").
      # * <tt>:use_two_digit_numbers</tt> - Set to true if you want to display two digit month and day numbers (e.g.
      #   "02" instead of "February" and "08" instead of "8").
      # * <tt>:use_short_month</tt>   - Set to true if you want to use abbreviated month names instead of full
      #   month names (e.g. "Feb" instead of "February").
      # * <tt>:add_month_numbers</tt>  - Set to true if you want to use both month numbers and month names (e.g.
      #   "2 - February" instead of "February").
      # * <tt>:use_month_names</tt>   - Set to an array with 12 month names if you want to customize month names.
      #   Note: You can also use Rails' i18n functionality for this.
      # * <tt>:month_format_string</tt> - Set to a format string. The string gets passed keys +:number+ (integer)
      #   and +:name+ (string). A format string would be something like "%{name} (%<number>02d)" for example.
      #   See <tt>Kernel.sprintf</tt> for documentation on format sequences.
      # * <tt>:date_separator</tt>    - Specifies a string to separate the date fields. Default is "" (i.e. nothing).
      # * <tt>:time_separator</tt>    - Specifies a string to separate the time fields. Default is "" (i.e. nothing).
      # * <tt>:datetime_separator</tt>- Specifies a string to separate the date and time fields. Default is "" (i.e. nothing).
      # * <tt>:start_year</tt>        - Set the start year for the year select. Default is <tt>Date.today.year - 5</tt> if
      #   you are creating new record. While editing existing record, <tt>:start_year</tt> defaults to
      #   the current selected year minus 5.
      # * <tt>:end_year</tt>          - Set the end year for the year select. Default is <tt>Date.today.year + 5</tt> if
      #   you are creating new record. While editing existing record, <tt>:end_year</tt> defaults to
      #   the current selected year plus 5.
      # * <tt>:discard_day</tt>       - Set to true if you don't want to show a day select. This includes the day
      #   as a hidden field instead of showing a select field. Also note that this implicitly sets the day to be the
      #   first of the given month in order to not create invalid dates like 31 February.
      # * <tt>:discard_month</tt>     - Set to true if you don't want to show a month select. This includes the month
      #   as a hidden field instead of showing a select field. Also note that this implicitly sets :discard_day to true.
      # * <tt>:discard_year</tt>      - Set to true if you don't want to show a year select. This includes the year
      #   as a hidden field instead of showing a select field.
      # * <tt>:order</tt>             - Set to an array containing <tt>:day</tt>, <tt>:month</tt> and <tt>:year</tt> to
      #   customize the order in which the select fields are shown. If you leave out any of the symbols, the respective
      #   select will not be shown (like when you set <tt>discard_xxx: true</tt>. Defaults to the order defined in
      #   the respective locale (e.g. [:year, :month, :day] in the en locale that ships with Rails).
      # * <tt>:include_blank</tt>     - Include a blank option in every select field so it's possible to set empty
      #   dates.
      # * <tt>:default</tt>           - Set a default date if the affected date isn't set or is nil.
      # * <tt>:selected</tt>          - Set a date that overrides the actual value.
      # * <tt>:disabled</tt>          - Set to true if you want show the select fields as disabled.
      # * <tt>:prompt</tt>            - Set to true (for a generic prompt), a prompt string or a hash of prompt strings
      #   for <tt>:year</tt>, <tt>:month</tt>, <tt>:day</tt>, <tt>:hour</tt>, <tt>:minute</tt> and <tt>:second</tt>.
      #   Setting this option prepends a select option with a generic prompt  (Day, Month, Year, Hour, Minute, Seconds)
      #   or the given prompt string.
      # * <tt>:with_css_classes</tt>  - Set to true or a hash of strings. Use true if you want to assign generic styles for
      #   select tags. This automatically set classes 'year', 'month', 'day', 'hour', 'minute' and 'second'. A hash of
      #   strings for <tt>:year</tt>, <tt>:month</tt>, <tt>:day</tt>, <tt>:hour</tt>, <tt>:minute</tt>, <tt>:second</tt>
      #   will extend the select type with the given value. Use +html_options+ to modify every select tag in the set.
      # * <tt>:use_hidden</tt>         - Set to true if you only want to generate hidden input tags.
      #
      # If anything is passed in the +html_options+ hash it will be applied to every select tag in the set.
      #
      # NOTE: Discarded selects will default to 1. So if no month select is available, January will be assumed.
