As far as I know, only Google News has the option to sort search results by date. This option is one of the "search tools". For other kind of search results, you could use the date that the web page was cached but this date show the most recent, not the first one.
For sorting Google News search results, from Filter your search results - Search Help
Add or remove filters
1. Do a search on Google.
2. Choose the type of result you want to see, like Images or News, by selecting a type under the search box. Click More to see extra choices.
3. Below the search box, click Search tools to see more filters you can apply to your search. The Search tools you see will be different based on your search and the filters you've already used, so you won't see all the options every time.
4. To remove any filters you've added through Search tools, click Clear.
