About TimeDateKit

Last updated: May 31, 2026

TimeDateKit is a small, focused collection of free date and time calculators. The goal is simple: give you a fast, trustworthy answer to a common date or time question, without an account, a paywall, or twelve interstitial pop-ups in the way.

What's here

• Date Calculator — days between two dates, add or subtract days, age, business-day counts, and countdowns to any date.
• Time Zone Calculator — convert a time across cities, plan meetings across zones, and read a DST-aware world clock.

How the calculators work

Every calculator runs in your browser using standard date-and-time logic and IANA time-zone data. Nothing you type leaves your device. There is no signup, no account, and no stored history of your inputs.

The results are intended as informational starting points. For anything where an exact deadline or legal date matters — a filing cutoff, a contract date, an international travel itinerary — confirm against an authoritative source for your situation.

Who runs TimeDateKit

TimeDateKit is built and maintained by Diego Alducin, an independent software developer based in San Antonio, Texas. It's part of a broader effort to publish small, dependable utility tools that just work on a phone or a laptop the first time you open them.

How it stays free

The site is supported by display advertising. Ads are clearly separated from the calculators and the underlying math; they do not influence results in any way. See the Privacy Policy for details on how advertising and analytics work here.
