I’ll start with a couple I’ve found for keeping up with atomic clock time, but this question isn’t limited to timekeeping, it can also relate to celestial events, weather, etc…
I do like the sleek and streamlined time.ms site, but according to their whois data, they only started that site a couple months ago, while time.gov has been around since 1999.
Long standing sites are preferable, but either way, what other live data sites do you people recommend?
My father was a Sr Meteorologist at EC for 40+ years and I loved learning from him. Here’s the Meteorological Service of Canada’s satellite weather data. So many things, start drilling down my friends!

A couple random IR & Visible loops you could fun around with to get some flavor. GOES-EAST and GOES-West. GOES means the Geostationary Operational Environmental Satellite.
Here’s some groovy details on the satellites: https://www.canada.ca/en/services/environment/weather/radar-satellites.html
The Met Service also provides MSC Open Data: https://eccc-msc.github.io/open-data/msc-data/readme_en/ “up-to-date information on past, present and future weather conditions, climate, water and environmental information over Canada and the world”. I wish I was still into programming hardcore, I’d go bonkers with the new data they make available.
