In Google Chrome, there's only an option to delete the newest cookies. I want to delete the oldest ones. How can I do that?
You might want to look for cookie manager software. You want one that will let you sort the cookies by creation date or modified date. Then you can just select all the cookies past a certain date and delete them.

In response to the comment from the OP, there is no way to remove cookies by date. Although you can remove them by site.
And if you must delete them by date, you can open each individual cookie and check the date it was created.
Open up Content Settings
Open All cookies and data
Open up any website and open the individual cookie and do what you want with it.
I do not believe you can delete history easily without deleting the time since that period. See the link for a explanation of how Chrome stores cookies maybe you can go through the directories and delete the time period you want.
