The DS1307 is a low power serial real time clock/calendar from Maxim Integrated with full binary coded decimal (BCD) clock/calendar plus 56 bytes of Non Volatile Static Random Access Memory.

Data and Address are transferred serially through a bidirectional I2C bus. The RTC provides year, month, date, hour, minute and second information. The end date of months is automatically adjusted for months fewer than 31 days including leap year compensation up to year 2100. It can operate either in 24-hour format or 12-hour format with AM/PM indicator.

The DS1307 allows a microcontroller project to keep track of time even if it is reprogrammed, or if the power is lost. It can be used in data-logging projects, clock, timers and alarms.
The DS1307 can be easily connected to any PIC microcontroller or Arduino with I2C bus interface.
