Need reliable electrical or mechanical 24hr timer

In summary, a 24hr timer is a device that automatically controls the on and off functions of an electrical or mechanical appliance within a set period of 24 hours. A reliable 24hr timer is necessary for energy savings and automation of daily tasks. It works through a clock mechanism and switch that activates the appliance at the designated time. It can be used for a variety of appliances and there are options available for outdoor use as well.

It needs to perform at least 50 cycles with a cumulative error of no more than [+\-] 30 minutes. This is for a home project.

Any suggestions of components?

I'm not sure I understand...why can't you use a clock (either electrical or mechanical)?

I would recommend considering using a digital timer with a built-in microcontroller and a precision crystal oscillator. This type of timer can provide accurate timekeeping and can be programmed to perform a specific number of cycles with minimal error. Additionally, using high-quality electrical and mechanical components can also help ensure reliable performance over a long period of time. It may also be beneficial to test the timer under different conditions and make adjustments as needed to ensure it meets the required specifications for your home project.
