Add 'em up, and then add the numbers for Feb and Aug.
What do you get?
Your text should tell you the difference between "exact" and "ordinary."
To calculate the exact number of days between two dates, you can follow the steps below:
Step 1: Determine the number of days in each month between the two dates.
In this case, let's count the days from 12 February 2012 to 26 August 2012.
Month | Days
--------------
February | 29 (since 2012 is a leap year)
March | 31
April | 30
May | 31
June | 30
July | 31
August | 26
Step 2: Sum up the number of days in each month.
29 + 31 + 30 + 31 + 30 + 31 + 26 = 208
So, the exact number of days from 12 February 2012 to 26 August 2012 is 208 days.
Now let's calculate the ordinary number of days between the two dates:
Step 1: Count the number of full months between the two dates.
Counting full months, we have March, April, May, June, July. That's 5 months between the two dates.
Step 2: Multiply the number of full months by the average number of days in a month (30.44).
5 months × 30.44 days/month = 152.2 days
Step 3: Count the number of remaining days after the last full month.
We have 26 days in August.
Step 4: Sum up the number of days from step 2 and step 3.
152.2 days + 26 days = 178.2 days
So, the ordinary number of days from 12 February 2012 to 26 August 2012 is approximately 178.2 days.
