the ds1307 (http://datasheets.maximintegrated.com/en/ds/ds1307.pdf) doesn't have alarm feature can't program turn load on or off @ specified time. think need 2 alarms , set/reset flipflop (or latching relay) want.
look ds1375 or ds1337 (or ds1337c includes crystal
look ds1375 or ds1337 (or ds1337c includes crystal
