What do 2023, 2017, 2006, 1995, and 1989 have in common?

Turns out that date-wise, they have everything in common. Those years and many more are exactly the same. I learned this by checking a Perpetual Calendar, a list that uses algorithms to compute the day of the week for any given year, month, and day of month. With a Perpetual Calendar, you can figure out which years are the same as the current one.

Reduce, Reuse, Recycle!

Ff you’re like me with a drawer full of old calendars to pretty or meaningful to throw away, you can bring them out to reuse again. 2023 is an especially compatible year, with several options from the near-past from which to choose.

    That’s pretty cool, we should have kept our old calendars.

    What a great idea Mollie. Lovely way for memories of your wonderful cats to live on too. I have just run out of space for another calendar that was just given to me yesterday. One of my Christmas presents from a girlfriend was a Cattitude calendar with January’s grumpy moggie saying “Does it look like I rise and shine?” Happy New Year from Lynn & sleepy cat Rambo!

    I was so glad to hear that I’m not the only one who keeps old calendars. 🙂
