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?
Realtime state of Nordic power system https://driftsdata.statnett.no/Web/map/snpscustom
I’m a big fan of Time and Date’s Night Sky page: https://www.timeanddate.com/astronomy/night/usa/knoxville
Great for learning about what stars/planets/comets/meteor showers/eclipses/etc should be visible from your location.
And if one is into stargazing, another handy resource is this Light Pollution Map: https://www.lightpollutionmap.info/
If you’re into weather tracking, I like both Windy and the regular NWS weather maps for (roughly) realtime weather maps.

That first one feels like a web version of Stellarium, there’s a desktop version and a mobile version and you can even check what’s going to happen ahead of time with them. If you get the mobile version you can even enable movement tracking to see exactly what you’re looking at by pointing the phone towards it.
National Institute of Standards and Technology is a good one:

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.
nullschool. By default, it shows air currents at surface level. You can also see some chemical levels on the atmosphere, like carbon monoxide, carbon dioxide; see ocean currents and waves, as well as temperature.

If you are anywhere near hurricane prone areas, this is the site where all the local meteorologists get their data and sometimes thier visuals: https://www.tropicaltidbits.com/analysis/models/
