In my experience you can use こんにちは as both hello and good afternoon. It is ually used between 10 am and 8 pm. Before 10 am people use good morning. And after 8pm people use good evening. This is a general unspoken standard that is not the case in each and every situation. Like with every language it depends on the context.
