The 2019–20 coronavirus pandemic changed everyone’s plans.
 
Many people bought 2020 planners, and regretted it. “Biggest waste of money: 2020 planner” was posted on Twitter by “Jean, like the pants” on March 20, 2020. “What a waste of money my 2020 diary planner was” was posted on Twitter by @angrydiydad on March 21, 2020.
 
Other people didn’t buy 2020 planners. “I’m glad I didn’t waste any money on a 2020 planner” was posted on Twitter by “social distancing bully” on April 1, 2020. Glad I didn’t waste my money buying a planner for 2020 was posted on Twitter by “whiskey in a tea cup” later on April 1, 2020.
   
“I’m not buying a 2021 planner until I see a trailer” is a related joke.
