Calculating a Future Date Based on Days Passed

The question asks us to determine the exact date when Faiz was born, given that he was born 553 days after Aizaz, who was born on January 5, 2015.

To find Faiz's birth date, we need to count 553 days forward starting from January 5, 2015.

Step-by-Step Calculation to Find Faiz's Birth Date

We will count the days month by month and year by year until we reach a total of 553 days after January 5, 2015.

Counting Days in the Year 2015

First, let's count how many days remain in the year 2015 starting from the day after January 5th (i.e., from January 6th). The year 2015 is not a leap year, so it has 365 days.

The number of days remaining in January 2015 after January 5th is \(31 - 5 = 26\) days.

Let's sum the number of days for the rest of the months in 2015:

• January (remaining): 26 days
• February (2015 is not a leap year): 28 days
• March: 31 days
• April: 30 days
• May: 31 days
• June: 30 days
• July: 31 days
• August: 31 days
• September: 30 days
• October: 31 days
• November: 30 days
• December: 31 days

Total number of days from January 6, 2015, through December 31, 2015:

\(26 + 28 + 31 + 30 + 31 + 30 + 31 + 31 + 30 + 31 + 30 + 31 = 360\) days.

So, 360 days after January 5, 2015, brings us to December 31, 2015.

Counting Remaining Days in the Year 2016

We need to count a total of 553 days after January 5, 2015. We have already counted 360 days within the year 2015.

The remaining number of days we need to count is:

\(553 - 360 = 193\) days.

These 193 days will fall within the year 2016, starting from January 1, 2016. We need to find the date that corresponds to the 193rd day of 2016.

Let's count the days month by month in 2016. The year 2016 is a leap year (divisible by 4), so February in 2016 has 29 days.

After accounting for 182 days in 2016 (from January 1st to June 30th), we have 11 days remaining to count (\(193 - 182 = 11\)).

These remaining 11 days will fall in the month of July 2016. Counting 11 days from the beginning of July 2016 (July 1st) brings us to July 11, 2016.

Conclusion: Faiz's Birth Date

Adding 553 days to January 5, 2015, results in the date July 11, 2016. Therefore, Faiz was born on July 11, 2016.

Revision Table: Summary of Date Calculation

The calculation confirms that 553 days after January 5, 2015, is July 11, 2016.

Additional Information: Importance of Leap Years in Date Calculations

When calculating dates over multiple years, it is crucial to identify whether the years involved are leap years. A leap year occurs every four years, with the exception of years divisible by 100 but not by 400. Leap years add an extra day (February 29th) to the calendar, making the year 366 days long instead of the usual 365. Including or excluding this extra day can significantly change the final calculated date, especially when dealing with large numbers of days like 553. In this problem, correctly identifying 2016 as a leap year was essential for an accurate result.
