For the date October 3rd, ten weeks ago would have been July 25th. (This answer would depend, obviously, on what day the question was asked.)
To determine the number of weeks until December 3rd, you need to know the current date. If today is, for example, October 27, 2023, there are about 5 weeks until December 3rd. You can calculate this by counting the days between the two dates and dividing by 7.
two weeks and six days
Labor Day in 2012 fell on September 3rd. To calculate the number of weeks between June 22nd and September 3rd, you find the total number of days, which is 73 days. Dividing 73 days by 7 days per week gives approximately 10.43 weeks. Therefore, there are about 10 weeks and 3 days between June 22nd and Labor Day 2012.

When the doctor counts you as 7 weeks, they are counting from your last period. I figured if the ultrasound says 7 weeks, that is from around sep. 7th, the 1st day of your last period. meaning between sep. 18th thru sep. 24th could have got you pregnant. Likely the 21st. However an ultrasound of 7 weeks on 25th October gives you a due date of 13th June not the 3rd. See the Related Link for "conception-calculator" to the right for more.
