If today is Saturday, what will be the day 350 days from now?

Key idea: A week has 7 days, so adding a multiple of 7 days returns to the same weekday.

• Compute 350 ÷ 7.

• 350 = 7 × 50, so the remainder is 0.

• A remainder of 0 means the weekday does not change. Therefore, 350 days from Saturday is Saturday.
