if a market is hold every four days and today is the market day which day in the week is the next five market days

helps plz

What day is today?

Is Sunday day #1 ?
Just keep adding 4.
When you get past 7, subtract 7 and keep going.

For example, if today is Thursday (#5), then the next market day is day #9
But 9-7 = 2, so it will be Monday.

Things are actually easier if you call Sunday day #0. Then you just add 4, divide by 7, and take the remainder.
