5. Find the approximate number of days from: a) July 25, 2004 to May 25, 2006 b) March 15, 2010 to September 12, 2013 c) October 13, 2011 to February 24, 2012

To find the approximate number of days between two dates, we'll count the number of days for each year, month, and day between the given dates.

### Problem 5: Approximate Number of Days Between Dates

#### Part a) July 25, 2004 to May 25, 2006

1. **From July 25, 2004, to July 25, 2005:**
   - This is exactly 1 year = 365 days (since 2004 is a leap year, but the period doesn't cover February 29).

2. **From July 25, 2005, to May 25, 2006:**
   - From July 25, 2005, to December 31, 2005: 
     - July 25 to July 31: 6 days
     - August: 31 days
     - September: 30 days
     - October: 31 days
     - November: 30 days
     - December: 31 days
     - Total: 159 days
   - From January 1, 2006, to May 25, 2006:
     - January: 31 days
     - February: 28 days (2006 is not a leap year)
     - March: 31 days
     - April: 30 days
     - May 1 to May 25: 25 days
     - Total: 145 days

Total number of days:
\[
365 + 159 + 145 = 669 \text{ days}
\]

#### Part b) March 15, 2010 to September 12, 2013

1. **From March 15, 2010, to March 15, 2011:**
   - Exactly 1 year = 365 days (2010 is not a leap year).

2. **From March 15, 2011, to March 15, 2012:**
   - 1 year = 366 days (2012 is a leap year).

3. **From March 15, 2012, to March 15, 2013:**
   - 1 year = 365 days.

4. **From March 15, 2013, to September 12, 2013:**
   - March 15 to March 31: 16 days
   - April: 30 days
   - May: 31 days
   - June: 30 days
   - July: 31 days
   - August: 31 days
   - September 1 to September 12: 12 days
   - Total: 181 days

Total number of days:
\[
365 + 366 + 365 + 181 = 1,277 \text{ days}
\]

#### Part c) October 13, 2011 to February 24, 2012

1. **From October 13, 2011, to December 31, 2011:**
   - October 13 to October 31: 18 days
   - November: 30 days
   - December: 31 days
   - Total: 79 days

2. **From January 1, 2012, to February 24, 2012:**
   - January: 31 days
   - February 1 to February 24: 24 days
   - Total: 55 days

Total number of days:
\[
79 + 55 = 134 \text{ days}
\]

### Summary of Results:

- **a)** July 25, 2004 to May 25, 2006: **669 days**
- **b)** March 15, 2010 to September 12, 2013: **1,277 days**
- **c)** October 13, 2011 to February 24, 2012: **134 days**
