About this tool
Timezone conversion uses the browser's built-in Intl API against the IANA timezone database, so results account for real historical and future daylight-saving rules rather than a fixed offset. The "Date → Unix timestamp" direction resolves the wall-clock time you enter as if it were local to the selected timezone; right at the instant of a daylight-saving transition, a wall-clock time can be genuinely ambiguous or nonexistent, and this tool resolves that case using the standard-time side of the transition, matching how most conversion tools handle it.
Nothing you enter is sent to a server — the entire tool runs as JavaScript in your browser tab.
