Society & Culture
Dates & Times, country facts, food nutrition, history and word tools are all live. This section is knowledge, not just calculation — so every figure is either sourced (UN population estimates, USDA food data) and labelled, or calculated on the page where you can check it. Arts & Media remains marked v0.4 until its data can meet the same bar.
