... first and third Sundays ...

Yes, it is correct to say "Meetings will be held on the 1st and 3rd Sunday of the month." In this phrase, you are specifying that the meetings will take place on two specific Sundays each month: the first Sunday and the third Sunday.

To determine the 1st and 3rd Sunday of the month, you can follow these steps:

1. Identify the current month.
2. Find the first Sunday of the month.
- Start with the first day of the month and check if it falls on a Sunday.
- If not, proceed to the next day until a Sunday is found.
3. Determine the third Sunday of the month.
- Start with the first Sunday of the month and count two Sundays ahead.

By following these steps, you can accurately determine the dates of the 1st and 3rd Sunday for any given month.
