To calculate the number of seconds in a year, start with the number of seconds in a minute (60), multiply by the number of minutes in an hour (60), then by the number of hours in a day (24), and finally by the number of days in a year (approximately 365). This gives 60 * 60 * 24 * 365 = 31,536,000 seconds, which is about 30 million.
