current = Date.parse(datequery())

if(maxdate<target)
  screenshot_and_raise "Target date'#{target}' is larger than maximum date'#{maxdate}' in date picker"
end

limit = 100
# => set year
  count = 0
  dir = (target.year < current.year) ? "down" : "up"
  until (target.year == Date.parse(datequery()).year) or (count==limit)  do
      date = Date.parse(datequery())
      scroll_date_component(dir, 2, date.year)
#      puts("Inside the loop1 '#{count}'=> '#{date.year}'" )
    count += 1
  end

# => set month
  count = 0
  dir = (target.month < current.month) ? "down" : "up"
