About this product
A module built around the DS1307 serial real-time clock chip. It keeps track of seconds, minutes, hours, date, month and year over an I2C bus, adjusts for leap years, and switches to a backup supply during power failures so timekeeping continues.

How do I wire the DS1307 module to an Arduino?
Connect VCC to 5 V, GND to GND, SDA to the I2C data pin and SCL to the I2C clock pin. On an Arduino UNO, SDA is A4 and SCL is A5.
Does the clock keep time when the main power is off?
Yes, if a backup supply is connected to the module. The DS1307 detects power failure and automatically switches to the backup supply, so timekeeping continues.
