A month is not as clearly defined as a week, a day, or a year. In other words, any answer will be an approximation, an estimate.
Decide how many days per month you want to calculate, for example 30, or 30.5. Let's say you pick 30. Then multiply 7 (months) x 30 (days/month) x 24 (hours/day) x 60 (minutes/hour) x 60 (seconds/minute).
If you memorize that a day has 86400 seconds, then you can do the calculation somewhat shorter: 7 (months) x 30 (days/month) x 86400 (seconds/day).
For Non Leap Years, here is what we have, if you start on the first of a month, then there are 7 time periods, where seven months = 212 days, which is 18,316,800 (from the 86,400 seconds per day). There are 4 time periods (starting March 1, April 1, May 1, June 1) which have 214 days in seven months: 18,489,600 seconds. There is one time period (July 1 through Jan 31) which has 215 days: 18,576,000 seconds. If your time period contains a February in a Leap Year, then you'd need to add 86,400 seconds to your answer. Over time, on average, there are approx 30.43666... days in a month, which is 213.0567 days or 18,408,096 seconds, for seven months.

How many seconds in a 1000 years?
There are 60 seconds in a minute.
There are 60 minutes in an hour. 60 * 60 = 3600, so there are 3600 seconds in an hour.
There are 24 hours in a day. 24 * 3600 = 86400, so there are 86400 seconds in a day.
There are approximately 365.2425 days in a year. 365.2425 * 86400 = 31556952, so there are approximately 31556952 seconds in a year.
This means that in 1000 years, there are approximately 31556952 * 1000 seconds, which equals 31556952000, or thirty-one billion, five-hundred-and-fifty-six million, nine-hundred-and-fifty-two thousand seconds in a thousand years.
