Real-time alarm clock is a feature that can be used to allow the computer to 'wake up' after being shut down to perform tasks on a daily or a certain day. Sometimes it can be found in the 'Power Management' section of the motherboard BIOS settings. However, newer BIOS settings do not include RTC alarm options, although they can still be set from within the user's app. Wake On LAN, Wake on ring, and IPMI functions can also be used to start the computer after it is turned off.
In Linux, real time clock alarms can be set or retrieved using/proc/acpi/alarm or/sys/class/rtc/rtc0/wakealarm. Or the rtcwake utility can be used which prevents problems when using local time instead of UTC by automatically processing the /etc/adjtime file. systemd can be used to build the system and run the task at any given time.
In Microsoft Windows there are various programs that can be used to 'wake up' the computer from standby or hibernation. The Task Scheduler settings for power management can be used to 'Build a computer to perform this task'.
