How it works
- Set the start and end in UTC. Both endpoints can be selected when they fall on the interval.
- Choose an interval and quantity. Settings holds unique results, ordering and output format.
- Generate, then copy ISO timestamps or Unix seconds, or export the current result.
Equal chances for each time slot
Slots start at your chosen start time and advance by the interval. Every eligible slot has the same chance. The end is included only if a slot lands on it. UTC avoids ambiguous or missing local times around daylight saving changes.
Your inputs stay with you
Your entries, settings and results are processed in this browser and are not sent to our server. Clearing browser data removes saved drafts and results. Export a text file if you want to keep a copy. Hosting may record standard page-request logs.
Does this use my local timezone?
No. The input fields are explicitly interpreted as UTC, regardless of your device timezone. ISO output ends in Z. Unix output is whole seconds since 1970-01-01T00:00:00Z and can be negative before 1970.
