Answer

To find the day of the week on 7th March 2004 given that 6th March 2005 is a Monday, we can follow these steps:

### Step 1: Identify the date difference
We need to find the difference between 6th March 2005 and 7th March 2004. The difference is 1 year and 1 day (from 7th March 2004 to 6th March 2005).

### Step 2: Calculate the total number of days
Since 2004 is a leap year, it has 366 days. The number of days from 7th March 2004 to 6th March 2005 is:
- From 7th March 2004 to 7th March 2005: 366 days
- Since we want to go to 6th March 2005, we subtract 1 day, resulting in 365 days.

### Step 3: Calculate odd days
To find the odd days in 365 days, we divide 365 by 7:
- 365 ÷ 7 = 52 weeks and 1 day
- This means there is 1 odd day.

### Step 4: Determine the day of the week
Since 6th March 2005 is a Monday, we subtract the 1 odd day to find the day of the week for 7th March 2004:
- Monday - 1 day = Sunday.

### Conclusion
Therefore, the day of the week on 7th March 2004 was **Sunday**.
