Sir, we are Q/A Contributers not the bots. Search Google, try to make a code even with half knowledge, show us then we will be happy to help you. There are thousands of threads to answer if we will post a to replica of a question then we will not be able to answer the questions, which can't be Searched on Google. Anyway I will give the direct link to the answer of your question.
Python → https://stackoverflow.com/questions/5166842/sort-dates-in-python-array
C# → https://stackoverflow.com/questions/14667754/sort-string-list-with-dates-in-c-sharp
Before blaming me or any other contributor you should take a look at your question. It's badly formated, no description with Missing "date" in your title (Instead of data) and not included the language. (it's different in every language).
I will waste time in understanding your question then will waste time in asking for language then posting a answer to a question which can be easily Searched. You should understand our problems also. I will really happy to help you, if you tried to make a code but with no attempt. It easy to answer such questions but also it feels boring to do it multiple times.
Hope you understand. ^_^
