What Does Mark Your Calendars Mean?
Mark your calendars means remember a particular date because something important or interesting will happen on that day.
The expression comes from the simple idea of writing an important date on a calendar so you do not forget it. Today, people use it both literally and figuratively.
For example:
- Mark your calendars for the annual conference on September 18.
- Mark your calendars for our next team meeting.
- Mark your calendars for the school fundraiser.
- Mark your calendars because registration opens next Monday.
The phrase does not usually mean that someone must physically write the date on a paper calendar. It simply encourages people to remember the date or add it to their digital calendar.
Basic Explanation
The phrase has two main parts:
- Mark means to highlight, note, or remember something.
- Your calendars refers to whatever calendar system you use, such as a phone calendar, work calendar, planner, or physical calendar.
So, the simple meaning is:
Remember this date because something is happening.
It often appears before the date of an event.
For example:
Mark your calendars for October 12.
This tells the reader that October 12 matters and they should make a note of it.
