CronCraft is a lightweight, developer-friendly .NET SDK that converts cron expressions into human-readable strings — with support for localization, formatting, and time zone awareness — no configuration files required.

CronCraft is designed for clarity, speed, and minimal setup.

Whether you're building a web app, a CLI tool, a Windows Service, or a background worker — just create a CronSettings object, and you're good to go.

❝ No dependency injection. No appsettings. Just clean, functional cron parsing. ❞

• 🔄 Converts standard or Quartz cron expressions to plain language
• 🌍 Localized day-of-week formatting (short, full, single, or custom)
• 🕘 Time zone adjustment (optional)
• 🔧 Fully configurable via CronSettings object
• 📦 Lightweight, zero-dependency core logic

dotnet add package CronCraft

using CronCraft.Models;
using CronCraft.Extensions;

string cronExpression = "0 0 * * *"; // Every day at midnight

var settings = new CronSettings
{
    Language = "en",
    DayNameFormat = "short"
};

// Without timezone
string humanReadable = cronExpression.ToHumanReadable(settings);
Console.WriteLine("🔁 CronCraft Expression Translator");
Console.WriteLine("-----------------------------------");
Console.WriteLine($"🧾 Cron Expression:   {cronExpression}");
Console.WriteLine($"📖 Human Readable:    {humanReadable}");
Console.WriteLine("-----------------------------------");
Console.WriteLine("Press Enter to exit...");

// With TimeZone
TimeZoneInfo timeZone = TimeZoneInfo.FindSystemTimeZoneById("W. Central Africa Standard Time");
humanReadable = cronExpression.ToHumanReadable(settings, timeZone);
Console.WriteLine($"📖 Human Readable (Local TZ): {humanReadable}");

Console.ReadLine();

Expected Output:

🔁 CronCraft Expression Translator
-----------------------------------
🧾 Cron Expression:   0 0 * * *
📖 Human Readable:    Every day at 12:00 AM
-----------------------------------
📖 Human Readable (Local TZ): Every day at 01:00 AM
Press Enter to exit...

• full: e.g. "Sunday"
• short: e.g. "Sun"
• single: e.g. "S"
• custom: fully user-defined via Dictionary<string, string>

• English (en)
• Spanish (es)
• French (fr)
• Easily extendable via custom mappings
