A cron expression parser and job scheduler library for Go that runs functions on scheduled schedules. Version 3 supports standard cron specs, optional seconds fields, timezone handling, and chainable job wrappers for cross-cutting behavior.

Use cases

• run a function every night at midnight in go
• schedule recurring background jobs in go
• parse cron expressions in go
• run periodic cleanup tasks in my application
• skip overlapping job runs in a scheduler
• schedule jobs with timezone support in go

When to choose

• you need in-process scheduled jobs in a Go application
• you want standard cron syntax with optional seconds precision
• you need interceptors for panic recovery or skipping concurrent runs

When to avoid

• you need a distributed scheduler across multiple nodes
• you need system-level cron replacing the OS crontab
• you need Quartz year-field support
