## Overview

We use the **`sunday?` method** to learn if today or a time object is Sunday or represents Sunday. The method returns a Boolean value `true` or `false`. If the time object is Sunday, `true` is returned. Otherwise, `false`.

## Syntax

## Parameters

**`t_o`**: This is the time object we want to check for representing Sunday.
## Return value
The value returned is a Boolean value. If the time object is Sunday, `true` will be returned. Otherwise, `false` will be returned.

## Code example

# create time objects
t1 = Time.now  # current time
t2 = Time.new(1990)
t3 = Time.new(1990, 4, 1) # sunday in 1998
t4 = Time.new()

# call the "sunday?" method
# and print result
puts t1.sunday?  
puts t2.sunday?  
puts t3.sunday?  
puts t4.sunday?  

## Explanation
* line 2-5: We create time objects using the `Time.now` or the `Time.new()` methods.
* line 9-12: We use the `sunday?` method to check if the time objects we create are actually Sunday or not. Then we printed the results.
