To find the day of the week after a specific number of days, we utilize the repeating 7-day cycle of the week.
We need to determine the net change in days. Since the week repeats every 7 days, we find the remainder when the given number of days (16) is divided by 7.
Calculation: $16 \div 7$
Using the division algorithm: $16 = (2 \times 7) + 2$
The remainder is 2. This means that after 16 days, the day will be shifted forward by 2 days from the starting day.
The starting day is Thursday. We need to find the day that is 2 days after Thursday.
Therefore, after 16 days from Thursday, the day will be Saturday.
