Answer

To find out what day of the week it was on January 12, 1979, given that January 1, 1992, was a Wednesday, we can follow these steps:

### Step 1: Calculate the number of years between 1992 and 1979
We first need to find the difference in years between January 1, 1992, and January 1, 1979.

- 1992 - 1979 = 13 years

### Step 2: Determine the number of leap years in that period
Next, we need to find out how many leap years occurred between 1979 and 1992. A leap year is any year that is divisible by 4, except for end-of-century years, which must be divisible by 400.

The leap years between 1979 and 1992 are:
- 1980
- 1984
- 1988

So, there are 3 leap years.

### Step 3: Calculate the total number of days
Now we can calculate the total number of days from January 1, 1979, to January 1, 1992.

- Total years = 13
- Total days from non-leap years = (13 - 3) * 365 = 10 * 365 = 3650 days
- Total days from leap years = 3 * 366 = 1098 days

Adding these together gives us:
- Total days = 3650 + 1098 = 4748 days

### Step 4: Find the number of weeks and extra days
Now, we divide the total number of days by 7 to find out how many weeks and extra days there are.

- 4748 ÷ 7 = 678 weeks and 2 days

This means there are 2 extra days beyond complete weeks.

### Step 5: Determine the day of the week
Since January 1, 1992, is a Wednesday, we can count backward 2 days to find the day on January 1, 1979.

- Wednesday (1 day back) = Tuesday
- Tuesday (2 days back) = Monday

So, January 1, 1979, was a Monday.

### Step 6: Calculate the day for January 12, 1979
Now we need to find out what day it was on January 12, 1979. From January 1 to January 12, there are 11 days.

- Starting from Monday (January 1), we count 11 days:
- Monday (1)
- Tuesday (2)
- Wednesday (3)
- Thursday (4)
- Friday (5)
- Saturday (6)
- Sunday (7)
- Monday (8)
- Tuesday (9)
- Wednesday (10)
- Thursday (11)
- Friday (12)

Thus, January 12, 1979, was a **Friday**.

### Final Answer:
**January 12, 1979, was a Friday.**
