To calculate the total number of days worked between January 8th and March 19th, we can break it down by months:

1. January 8th to January 31st:

   • January has 31 days.
   • Days worked in January = $31 - 8 + 1 = 24$ days.

2. February:

   • February has 29 days in a leap year or 28 days in a common year.
   • Assuming it's a common year (28 days), all 28 days of February are included.

3. March 1st to March 19th:

   • Days worked in March = 19 days.

Total:

• January: 24 days
• February: 28 days
• March: 19 days

$24 + 28 + 19 = 71 \text{ days}$

So, you worked 71 days in total.
