Date & Time Toolkit
Timestamps, timezones, and cron schedules — five tools for the two date-and-time problems every backend eventually runs into. All run entirely in your browser.
How these fit together
Two clusters here. Unix Timestamp Converter and Timezone Converter handle a single point in time — turning a Unix timestamp into something readable, or converting a date and time across timezones. The other three handle recurring schedules: Cron Parser translates an existing cron expression into plain English and shows upcoming run times, Cron Builder goes the other direction — pick a schedule, get the expression — and Cron Validator checks an existing expression or a full crontab file for structural mistakes before they reach a server.
