Python Program to Convert Days to Hours Minutes Seconds

You can convert days to hours, minutes, and seconds in Python by multiplying days by 24 for hours, then by 60 for minutes, and again by 60 for seconds, like hours = days * 24, minutes = hours * 60, and seconds = minutes * 60.

Examples

Input1

Output1 day = 24 hours, 1440 minutes, 86400 seconds

Input3

Output3 days = 72 hours, 4320 minutes, 259200 seconds

Input0

Output0 day = 0 hours, 0 minutes, 0 seconds

How to Think About It

To convert days into hours, minutes, and seconds, first understand that 1 day has 24 hours, each hour has 60 minutes, and each minute has 60 seconds. So multiply the number of days by 24 to get hours, then multiply hours by 60 to get minutes, and finally multiply minutes by 60 to get seconds.

Algorithm

1

Get the number of days as input.

2

Calculate hours by multiplying days by 24.

3

Calculate minutes by multiplying hours by 60.

4

Calculate seconds by multiplying minutes by 60.

5

Display the results.

Code

python

days = int(input("Enter number of days: "))
hours = days * 24
minutes = hours * 60
seconds = minutes * 60
print(f"{days} day{'s' if days != 1 else ''} = {hours} hours, {minutes} minutes, {seconds} seconds")

Output

Enter number of days: 3
3 days = 72 hours, 4320 minutes, 259200 seconds

Dry Run

Let's trace the input 3 days through the code

1

Input days

days = 3

2

Calculate hours

hours = 3 * 24 = 72

3

Calculate minutes

minutes = 72 * 60 = 4320

4

Calculate seconds

seconds = 4320 * 60 = 259200

5

Print result

"3 days = 72 hours, 4320 minutes, 259200 seconds"

Variable	Value
days	3
hours	72
minutes	4320
seconds	259200

Why This Works

Step 1: Convert days to hours

Since 1 day has 24 hours, multiply the number of days by 24 to get total hours.

Step 2: Convert hours to minutes

Each hour has 60 minutes, so multiply hours by 60 to get total minutes.

Step 3: Convert minutes to seconds

Each minute has 60 seconds, so multiply minutes by 60 to get total seconds.

Alternative Approaches

Using total seconds calculation first

python

days = int(input("Enter number of days: "))
total_seconds = days * 24 * 60 * 60
hours = total_seconds // 3600
minutes = (total_seconds % 3600) // 60
seconds = total_seconds % 60
print(f"{days} day{'s' if days != 1 else ''} = {hours} hours, {minutes} minutes, {seconds} seconds")

This method calculates total seconds first and then breaks it down, useful if you want to handle partial days or seconds.

Using datetime.timedelta for conversion

python

from datetime import timedelta
days = int(input("Enter number of days: "))
time = timedelta(days=days)
hours = time.total_seconds() // 3600
minutes = (time.total_seconds() % 3600) // 60
seconds = time.total_seconds() % 60
print(f"{days} day{'s' if days != 1 else ''} = {int(hours)} hours, {int(minutes)} minutes, {int(seconds)} seconds")

This uses Python's built-in timedelta for more robust time calculations.

Complexity: O(1) time, O(1) space

Time Complexity

The program performs a fixed number of arithmetic operations regardless of input size, so it runs in constant time O(1).

Space Complexity

Only a few variables are used to store intermediate results, so space complexity is O(1).

Which Approach is Fastest?

All approaches run in constant time, but direct multiplication is simplest and fastest for this problem.

Approach	Time	Space	Best For
Direct multiplication	O(1)	O(1)	Simple and fast conversions
Total seconds then breakdown	O(1)	O(1)	Handling partial days or seconds
Using timedelta	O(1)	O(1)	Robust time calculations with built-in library
