Simple Javascript Coding

I have a php script that dynamically generates a json file that references certain web content to be displayed througout the day for each day of the week. For example, the json file might look like this: {"days":[ {"sun":[ {"id":1,"start":0}, {"id":3,"start":1145}, {"id":1,"start":1700} ]}, {"mon":[ {"id":1,"start":0} ]} {"tue":[ {"id":1,"start":0}, {"id":3,"start":1145}, {"id":1,"start":1700} ]}, {"wed":[ {"id":1,"start":0}, {"id":3,"start":1145}, {"id":1,"start":1700} ]}, {"thur":[ ]}, {"fri":[ {"id":1,"start":0} ]}, {"sat":[ {"id":1,"start":0} ]}, ]} I need javascript developed that would read a json file similar to this and redirect the page to the appropriate content based on the day and time of the week. So according to the above json, if a visitor came to the site at 12pm on Tuesday, they would need to be redirected to the webpage referenced with content id 3. I can modify the json file format if needed. The above is only an example.
