这可能会有所帮助

# In order to generate
# year = 2014
# months = "April/July"
# days = "24-1"

/(?<year>\d{4})\s*(?<months>\w+\/\w+)\s*(?<days>\d{1,2}\-\d{1,2})/ =~ "2014 April/July  24-1"

date1 = "#{year} #{months.split('/')[0]} #{days.split('-')[0]}"
date2 = "#{year} #{months.split('/')[1]} #{days.split('-')[1]}"

start_date = Date.strptime(date1, "%Y %b %d") #=> Thu, 24 Apr 2014
end_date = Date.strptime(date2, "%Y %b %d")   #=> Tue, 01 Jul 2014
