Plugin Required

Hi there i very new to wordpress and i busy making a blog for my holiday. and i need some help with a plugin, I am not sure what to look for so please help

This is what I need

I would like to create a Calendar the is not linked to google calendar or anything. I would like to just add stuff to do it like 09:00 – 10:00 on 20 March was at the Park or something. The will be my Calendar so when a user click on “At the Park “ is can take you to the Page or Post . I would like to have an option weather or not to put time.

So my page will be a calendar and i can login in the back and add stuff to a date which will show in the front ( will be nice to have each entire in a new color )
