Why this tool exists
Convert To Seconds keeps calendar durations and script-ready TTLs aligned. Enter days or hours once, reuse the total seconds anywhere.
Schedule planners
Turn maintenance windows or deployment delays into total seconds for scripts.
Rate limiter tuning
Calculate TTLs or retry timeouts from human-readable durations.
Automation inputs
Provide queue delays, cron offsets, or cache grace periods without manual math.
Quick start
Fill the calendar form, submit, and grab the total seconds for rate limiters, TTLs, or automation scripts.
- Open Convert To Seconds and enter years/months/days/hours/minutes/seconds—blank fields default to zero.
- Use Sample presets (TTL failover, standard DNS, CDN warm cache, hourly rotation) to populate realistic values instantly.
- Submit to see the total seconds, copy the numeric result, and reuse it in configs or APIs.
Supported inputs
- Accepts large calendar values (supports billions of seconds via server-side validation).
- Ignores blank fields by treating them as 0 so you can focus on the units that matter.
- Prevents negative or non-numeric inputs by returning error guidance near the form.
Mode 01
Calendar input
- Each unit (years → seconds) has its own labeled input and optional description for context.
- Reset returns the form to the state you loaded, keeping defaults handy for quick recalculations.
- Presets highlight TTL-friendly examples so infrastructure teams can load standard patterns instantly.
Presets & outputs
Presets map common TTLs; the output card surfaces both total seconds and descriptive breakdowns.
- The result card shows the total seconds plus a breakdown summary for cross-checking.
- Conversions list equivalent durations (minutes, hours, days, etc.) for communication-friendly copy.
- Copy buttons exist for both the total seconds and the formatted summary.
Field notes
Helpful habits for TTL conversions and automation math.
- Use presets as a starting point, then tweak units before copying the final seconds.
- Share both the total seconds and the breakdown in release notes so non-engineers can follow along.
- Pair this tool with Convert From Seconds to sanity-check TTL math in both directions.
