About This Tool

The Time Duration Converter lets you instantly convert any time duration between seconds, minutes, hours, days, weeks, months, and years. Whether you are calculating project timelines, converting workout durations, figuring out subscription periods, or solving time-related math problems, this tool provides fast and accurate results.

Our converter handles all standard time units with precise conversion factors. For units with variable lengths (months and years), we use widely accepted averages: one month equals 30.4375 days and one year equals 365.25 days (accounting for leap years). This provides reliable approximations suitable for most practical purposes.

Time duration conversion comes up frequently in project management, fitness tracking, scientific calculations, payroll, and everyday planning. How many hours will a 6-week project take? How many days is a 10,000-minute warranty? How many weeks until a deadline that is 90 days away? This converter answers all of these questions in seconds.

Formula / How It Works

1 day = 24 hours = 1,440 minutes = 86,400 seconds | 1 week = 7 days | 1 month = 30.4375 days | 1 year = 365.25 days

Frequently Asked Questions

There are exactly 86,400 seconds in one day. This is calculated as 24 hours x 60 minutes x 60 seconds = 86,400 seconds.
A standard year has 8,760 hours (365 days x 24 hours). A leap year has 8,784 hours (366 days x 24 hours). Our converter uses the average year length of 365.25 days, giving 8,766 hours per year.
There are approximately 52.1775 weeks in a year (365.25 days divided by 7). This is commonly rounded to 52 weeks, but the extra day (or two in a leap year) means a year is slightly more than 52 complete weeks.
Since months vary in length (28-31 days), our converter uses the average month length of 30.4375 days (365.25 days divided by 12). For precise date calculations, use our Date Difference Calculator instead.
There are exactly 10,080 minutes in one week. This is calculated as 7 days x 24 hours x 60 minutes = 10,080 minutes.
