Distance Between Coordinates Calculator

Compute the distance between two latitude/longitude points using Haversine (great-circle), Euclidean (flat-Earth approximation), or Manhattan (city-block) formulas. Returns kilometres on a spherical Earth model — accurate to within ~0.5% for most use cases.

Timezone Offset Calculator

Convert a time from one timezone to another given the UTC offsets of both. The simplest case of timezone arithmetic — useful for cross-time-zone meetings, travel planning, and reading wall-clock times across regions.
