The absolute best calendar I ever had was the free one from the welding supply company AirGas. Truly stunning photography of hot welding action. And the calendar itself was chock full of useful info like week numbers, holidays in the USA, Canada, and beyond. And overall, it was a large format that’s suitable for marking up and handwriting entries.

I’m only sorry that I wasn’t able to get the 2026 version due to business sending me away during January.
