ABOUT THE TOOL

One moment.
Clear local times.

Good Time helps people turn a time in an email into a dated appointment they can understand. Start with two locations and add up to ten. Search a city, country or time-zone abbreviation in one place.

How conversions work

The converter resolves a local date and time in the selected source zone into a single instant, then displays that instant in each destination zone. Named zones use IANA identifiers and the rules available through your browser’s time-zone support. Fixed-offset options keep the chosen offset instead of following seasonal changes.

When a clock change makes a local time impossible, we ask you to choose another time. When a local time occurs twice, we ask which occurrence you mean. Always check the destination date when a result crosses midnight.

Accuracy and future dates

Governments can change time-zone rules. Browser and operating-system updates affect the rules available to this tool. Keep your software current and reconfirm important future appointments. This is a scheduling aid, not an official time service or a guarantee about future policy.

Our guides

Guides explain specific scheduling problems, provide dated examples, and link to relevant sources. Examples are checked against the conversion engine during development. Publication dates identify the edition of each guide; they do not imply continuous verification of government rules.

For authoritative background, see the IANA Time Zone Database, UK government clock-change dates, and NIST’s US daylight-saving explanation.
