A Calendar is a thing were you can write down what you have to do like go shopping or if you are going to a party or something, I don't know.

It will help you remember what to do everyday so in my opinion
get a calendar!
1. "Nichole, aren't you going to write that down in your calendar?"

2. "I need a new calendar because the year is over!"

3. "I almost forgot what I had to do but I just looked at my calendar and I knew!"

When making plans, to confirm that you have set the time and date, and entered it into your itinerary - you say it's been "calendared."
Meet at 7pm on Sunday? No problem, calendared.

Useless pieces of paper. Whoever buys them shouldn't. Just get a digital watch.
Also, they're supposed to tell you the date. You should already know the date.
Never buy them. They are a waste of money.
Calendars are bad.

"But grandma, I was just calendaring! Your birthday is coming up, and I didn't want to forget."
