I love https://www.timeanddate.com https://www.timeanddate.com , they have surprisingly much nice content. Lots of stuff probably possible to find elsewhere, but it's a nice collection of utility. - Use their calendars all the time for various planning or visualizations. Like before exams I used to print one out, mark each exam, and work backward which days I would study for which subject. - The astronomy stuff is super useful. https://www.timeanddate.com/astronomy/night/ https://www.timeanddate.com/astronomy/night/ and it runs great on a phone. Aka I can be outside and use this page to know exactly what I'm looking at in the sky, or use it to plan to see what will be visible tonight. - I have a simple timer counting down to our planned vacation. Just fun to go to the tab and daydream. - When various holidays or red days are. Especially those that move and aren't normally marked on a calendar. Like when this and that part of Norway has their winter break.
