(for example using a 555 in Astable we can create a 1 sec delay) so i need which harware i have to use in such a way that i can get a delay for 5hrs.. thanking you in advance.

The 4060 consists of an oscillator section and 14 ripple-carry binary counter stages. The oscillator configuration allows design of either RC or crystal oscillator circuits.
