Build a cron schedule with a visual editor or paste an expression to see it in plain English, with the next run times in any time zone. Supports seconds, L, #, and @daily-style macros.

“Every 15 minutes, between 09:00 and 17:59, Monday through Friday”
5 fields: minute hour day-of-month month day-of-week — or 6 with seconds first. Macros like @daily and @hourly work too.
Calculating the next run times…
Fields · 5
| Field | Value |
|---|---|
| Minute | */15 |
| Hour | 9-17 |
| Day of month | * |
| Month | * |
| Day of week | 1-5 |
Type an expression like */15 9-17 * * 1-5, choose a preset, or build it field by field with quick picks for each part.
The description updates as you type, and invalid fields are explained (for example, minutes must be 0–59).
See the next 5, 10, or 25 run times in your time zone or any other, with how long until each one — the easiest way to catch an off-by-one-hour mistake.
In order: minute (0–59), hour (0–23), day of month (1–31), month (1–12 or JAN–DEC), and day of week (0–7 or SUN–SAT, where 0 and 7 are Sunday). * means every value, */5 every fifth, 1-5 a range, and 1,15 a list. A sixth field at the start adds seconds.
Cron runs in the server's time zone — often UTC on cloud servers and containers. Pick the server's zone in Time zone to see the real run times. Around daylight-saving changes, jobs scheduled in the skipped or repeated hour may run zero or two times.
Standard cron runs when either matches (OR, not AND). So 0 9 1 * 1 runs on the 1st and on every Monday.
Kubernetes CronJobs, GitHub Actions, and Linux crontab use the standard 5-field format shown here. Quartz and Spring put seconds first (6 fields), which is supported. AWS EventBridge uses a different 6-field format with a year and ?, so convert it first.
Data
Format, validate, and minify JSON in your browser. Paste it, upload a file, or load it from a URL. Errors show the exact line and column.
C# / .NET
Paste JSON and get C# model classes or records, ready for System.Text.Json or Newtonsoft.Json. Nested objects, arrays, nullable types, dates, and GUIDs are inferred for you.
SQL
Format and beautify SQL queries for SQL Server (T-SQL), PostgreSQL, MySQL, Oracle, and more. Set the indentation, keyword case, and layout, and get the exact line of any syntax error.
Data
Format, validate, and minify XML (config files, .csproj, SOAP, RSS) in your browser. Entities, CDATA, and mixed content are kept exactly as written, and errors show the line and column.
Data
Format and validate YAML (docker-compose, Kubernetes, GitHub Actions) without losing comments, or convert YAML to JSON. Errors show the exact line and column.
Web
Beautify HTML pages and fragments without changing how they render. Inline spacing, <pre>, and scripts stay intact, and embedded CSS and JavaScript can be formatted too.
