Answer:

The first day of the Year or Month January is Monday.

Step-by-step explanation:

Given:

January has exactly 4 Thursday and 4 Sundays.

To find: First day of the Year or Month January.

We know that there are exactly 4 weeks in a month of 30 days.

We also knows that there are 7 days in a week.

Number of days in 4 week = 4 × 7 = 28 days

Number of days in Month January = 31

So, we left with 31 - 28 = 3 days.

If month starts with Monday then after 4 week we have Monday , Tuesday , Wednesday for last 3 days which also has exact 4 Thursday and 4 Sundays.

If month starts with Tuesday then after 4 week we have Tuesday , Wednesday , Thursday for last 3 days which has 5 Thursday and exact 4 Sunday.

Similarly for any other day we don't have exactly 4 Thursday and 4 Sundays.

Therefore, The first day of the Year or Month January is Monday.
