A browser-based astronomy calculator for moon phases, sunrise, sunset, and golden-hour times by date and city.

Landing page captured for the 2026-09-03 issue.

Field notes

The site organizes several date-and-location calculations into separate tools: current moon phase, solar times, photographer-oriented golden-hour windows, and annual lunar calendars. It names ten-city coverage for the solar tools and lists full and new moons for 2027 and 2028. The homepage also states that calculations happen locally in the browser, with no location tracking, uploads, or account requirement.
