The contact transfer will be the most difficult, so we should start there. These steps are much easier to complete from a computer, rather then a phone or tablet.
Access the Gmail account that has the contacts you want to synchronize.
Click the "Gmail" drop-down menu on the left side of the window.
Click the "More" drop-down menu; then click the "Export" option.
Select the group you want to synchronize or choose "All contacts." The former gives you a drop-down menu with a list of all your contact groups; the latter will export every contact you have.
Click the "Google CSV" option if it's not selected already.
Click "Export"; then navigate to the location on your computer where you want to save your contacts. You can save the contacts file anywhere, and after you import it to the other Gmail account, you can delete the file if you prefer.
Access the second Gmail account.
Click the "More" drop-down menu; then click the "Import" option.
Click "Choose File" and then navigate to the file you just exported in the window that opens.
Click "Open," then click "Import."
Once that is done, your contacts will have moved over. Now for the calendar. Probably your best bet is just to share the calendar to the other gmail account.
Heres how to do so
Once you click Save, to access the calendar you will need to sign into your other gmail account. And then accept the share and view the calendar.. It will be in your other calendars section.

This wont effect the contacts or the calendars. Well, to be fair.. If you choose the permission option I mentioned, then any changes you made to the calendar in one place, would reflect in the other.
Or, you could simply export the calendar from the original account, and then import the calendar into the new account. By using export / import, it would be separate calendars altogether. You can find the export and import options on the calendar settings page, here
