- Added a Seasons section at /seasons: the four temperate seasons by hemisphere with both meteorological and astronomical 2026 dates, tropical wet and dry seasons, and desert hot and cool seasons, plus a live current-season indicator and every country grouped by its seasonal pattern.
- Each country calendar now shows a “Seasons in” block with the country's hemisphere and climate, its seasons and month ranges, and the current season.
- The 12-month calendar grid is now tinted by season, with a subtle animated motif on each month — falling snow in winter, leaves in autumn, blossoms in spring, a warm glow in summer, and rain in the tropical wet season. Animation is disabled for visitors who prefer reduced motion.
- Added a site-wide “Last updated” band above the footer showing the data date (machine-readable) alongside a note that all data is compiled and verified from official government sources — a freshness and provenance signal for search and AI answer engines.
