If you use it really often you can use the gem time_splitter to help you set some accessors of date, time, hour and minute for your datetime attributes. Hope it helps.

You can check the different Rails date formats from here : Rails Date Formats

Example :

time = Time.now
time.strftime("%d %B %Y")
# => 12 December 2016
