⏰ Time & dates

Cron expressions are the standard syntax for scheduling recurring background tasks in Unix systems, containers, web servers, and database pipelines. A minor formatting mistake—such as confusing minute and hour positions or misinterpreting step intervals—can cause batch jobs to run continuously or fail silently. Testing schedule expressions directly on production servers risks unexpected system load. This Cron Expression Parser interprets standard 5-field cron strings in your browser, translating each field into straightforward English explanations so you can verify automated schedules before deploying them to production.

Time Between Dates Calculator measures the gap between two dates and expresses it five ways: total days, total hours, total minutes, total seconds, and calendar months. Pick a start and an end with the two date-time pickers and click Calculate Difference — the difference is always taken as an absolute value, so the order does not matter. The months figure is a calendar-month count (year and month fields compared), while the other four are exact elapsed totals. It is useful for project timelines, age-in-days curiosity, and countdown checks. Everything computes locally in your browser.

Coordinating calls across regions means doing timezone math in your head — and getting it wrong means missed meetings. This timezone converter translates a time of day between eight major cities: UTC, New York, London, Paris, Los Angeles, Tokyo, Beijing, and Sydney. Pick a time, choose the source and target cities, and click Convert to see the equivalent local time. Daylight saving is handled automatically through your browser's timezone database, based on the current date.

Modern databases, cloud APIs, event logs, and authentication tokens routinely record time as Unix timestamps. While storing timestamps as numeric counts from the Unix epoch simplifies computer sorting and database indexing, these integers are impossible for humans to interpret at a glance. Determining whether a specific ten-digit number represents yesterday, last month, or next year often requires conversion into a human-readable date. This Unix timestamp converter simplifies timestamp-to-date conversion by turning raw epoch values into clear, human-readable dates. You can view converted dates in both UTC and your local system time. Because all conversions run entirely in your browser using client-side JavaScript, your timestamp data never leaves your device and is not transmitted to any server.
