Cronos is a .NET library for parsing Cron expressions and calculating their next occurrences. It handles time zones and daylight saving time transitions correctly, matching the behavior of *nix Cron, but does not include a job scheduler itself.

Use cases

• parse cron expressions in .NET
• calculate next occurrence of a cron schedule
• handle cron schedules across time zones
• handle daylight saving time transitions in scheduled jobs
• validate user-provided cron expressions
• compute cron schedule occurrences without a full scheduler

When to choose

• you need cron expression parsing and occurrence calculation in a .NET application
• correct time zone and DST handling is important for your schedules
• you want support for non-standard cron characters like L, W, #, and H
• you are building your own scheduler and need a reliable cron engine

When to avoid

• you need a full task or job scheduler, not just cron parsing
• you need Quartz.NET-style cron syntax compatibility with OR day matching
• your project is not on the .NET platform
