gocron

Provides a clean, idiomatic interface with fluent design, making it intuitive for Go developers to schedule jobs programmatically, as shown in the quick start example.

Supports multiple job types like cron expressions, random durations, and singleton modes, offering more control than basic timers for varied use cases.

Includes elector and locker interfaces for leader election and job locking, enabling robust multi-instance setups without single points of failure.

Comes with mocks and a fake clock interface, allowing reliable unit testing of scheduled jobs without real-time delays, as noted in the testing section.
