Idiom of the day

 "Call it a day" is an English idiom that means to stop working or doing an activity for the rest of the day. People use it when they feel they have done enough and want to finish.

Examples:

1. At work:

   • "We've been working on this project all day. Let's call it a day and continue tomorrow."
     (Meaning: Stop working now and finish later.)

2. In sports or exercise:

   • "I'm too tired to keep running. I think I'll call it a day."
     (Meaning: Stop running for now and rest.)

3. Casually in daily life:

   • "We've cleaned the house for hours. Let’s call it a day and relax."
     (Meaning: Stop cleaning and take a break.)

So, if you're done for today, you can say "I'll call it a day" to mean you're stopping now.
