Time to Minutes Converter: Hours, Days, Weeks & Years
1 day is 1,440 minutes, a 40-hour week is 2,400 minutes, and a 2,080-hour work year is 124,800 minutes. Enter any amount of time — seconds to years — and get the minutes, or work backwards from minutes.
How the time to minutes conversion works
Every unit of time converts to minutes by one multiplication, because the chain is fixed: 60 seconds make a minute, 60 minutes make an hour, 24 hours make a day, 7 days make a week. So 1 hour is 60 minutes, 1 day is 24 × 60 = 1,440 minutes, and 1 week is 7 × 1,440 = 10,080 minutes. Months and years are the only units that need a convention, because calendar months are 28 to 31 days and years are 365 or 366 days: this page uses the average month, 365.25 / 12 = 30.4375 days = 730.5 hours = 43,830 minutes, and the Julian year, 365.25 days = 525,960 minutes, which averages in leap years.
At the defaults — 1 day — the conversion is 1 × 1,440 = 1,440.00 minutes, which is 24.00 hours. The converter works both ways: type an amount and pick its unit, and it gives the minutes; or type minutes in the second box, and it gives the amount back in the unit you picked. Both boxes stay in sync, so you can convert in whichever direction you are thinking.
| Unit | Minutes | Hours | Days |
|---|---|---|---|
| 1 second | 0.02 | 0.00 | 0.00 |
| 1 minute | 1 | 0.02 | 0.00 |
| 1 hour | 60 | 1 | 0.04 |
| 1 day | 1,440 | 24 | 1 |
| 1 week | 10,080 | 168 | 7 |
| 1 month | 43,830 | 730.5 | 30.4375 |
| 1 year | 525,960 | 8,766 | 365.25 |
| Common conversion | Minutes | Hours |

| 40-hour week | 2,400 | 40 |
| 2,080-hour work year | 124,800 | 2,080 |
| 90 minutes | 90 | 1.50 |

The worked example, line by line
Setup: amount 1; unit day.
Line 1 — the conversion factor. 1 day = 24 hours × 60 minutes = 1,440 minutes.
Line 2 — minutes. 1 × 1,440 = 1,440.00 minutes.
Line 3 — hours. 1,440 / 60 = 24.00 hours.
Line 4 — days. 1,440 / 1,440 = 1.00 days — the answer, checked.
Line 5 — the reverse. 1,440 minutes / 1,440 = 1.00 day. Type the minutes and the day comes back.
Every branch, checked
40-hour week: 40 × 60 = 2,400 minutes. A standard full-time week is 2,400 minutes, before lunch breaks.
2,080-hour work year: 2,080 × 60 = 124,800 minutes. A full-time year is 52 weeks × 40 hours = 2,080 hours, which is 124,800 minutes.
90 minutes: 90 / 60 = 1.50 hours. A 90-minute meeting is an hour and a half.
15 minutes: 15 / 60 = 0.25 hours — one payroll quarter hour. Timesheets round to quarters, so 15 minutes is 0.25, 30 minutes is 0.50, and 45 minutes is 0.75.
465 minutes: 465 / 60 = 7.75 hours. A 7-hour-45-minute shift is 7.75 hours on a timesheet, not 7.45.
Reverse — 1,440 minutes: 1,440 / 1,440 = 1.00 day. The converter works in both directions: minutes back to days, hours, weeks, or years.
What the defaults assume
Seconds, minutes, hours, days, and weeks are exact: 1 minute is 60 seconds, 1 hour is 60 minutes, 1 day is 24 hours, 1 week is 7 days. Months and years use averages, and that is the only judgement call on the page: a month is 365.25 / 12 = 30.4375 days (730.5 hours, 43,830 minutes), because calendar months run 28 to 31 days; a year is 365.25 days (8,766 hours, 525,960 minutes), the Julian year, which averages in the leap day. A non-leap year is 365 days = 525,600 minutes, 360 minutes less — about 0.07% — so if you need an exact calendar year, use 525,600. Rounding convention: minutes to two decimals (whole numbers where exact), hours and days to two decimals, all computed from unrounded values.

Who uses this
- The payroll clerk rounding a timesheet: sees 15 minutes on a card and learns it is 0.25 hours — so the quarter-hour rounding is right, and 465 minutes is 7.75 hours, not 7.45.
- The project manager sizing a sprint: has a 40-hour week to plan and learns it is 2,400 minutes — so a 90-minute meeting is 1.50 hours of it, and the rest can be counted in minutes.
- The HR manager checking a work year: quotes a 2,080-hour year and learns it is 124,800 minutes — so the annual leave and overtime figures can be quoted in the same unit.
- The student converting a study block: has 90 minutes before an exam and learns it is 1.50 hours — so the revision plan in hours and the timer in minutes finally agree.
Accuracy & limitations
The math is exact for the numbers you enter: seconds, minutes, hours, days, and weeks convert by fixed factors, and the only approximation is the month and the year, which use the averages 30.4375 days and 365.25 days. A real calendar month is 28 to 31 days, so 43,830 minutes is the average month, not any particular month; a non-leap year is 525,600 minutes, 360 minutes less than the 525,960 used here. If you need exact calendar arithmetic — business days, holidays, time zones — use the business days calculator or the time to hours conversion page for the matching conversion.

How many minutes are in a day?
1,440 minutes. One day is 24 hours and one hour is 60 minutes, so 24 × 60 = 1,440. One week is 7 × 1,440 = 10,080 minutes.
How many minutes is a 40-hour week?
2,400 minutes. 40 × 60 = 2,400. That is the standard full-time week, before lunch breaks — and a 2,080-hour work year is 124,800 minutes.
How many minutes are in a work year?
124,800 minutes. A full-time year is 52 weeks × 40 hours = 2,080 hours, and 2,080 × 60 = 124,800 minutes.
How do you convert minutes to hours?
Divide by 60. 90 minutes is 90 / 60 = 1.50 hours, and 465 minutes is 465 / 60 = 7.75 hours. The converter works both ways: type the minutes and it gives the hours back.
What is 15 minutes in decimal hours?
0.25 hours. Timesheets round to quarter hours: 15 minutes is 0.25, 30 minutes is 0.50, and 45 minutes is 0.75. A 7-hour-45-minute shift is 7.75 hours, not 7.45.
How many minutes are in a month?
43,830 minutes, on average. The average month is 365.25 / 12 = 30.4375 days, which is 730.5 hours. A real calendar month is 28 to 31 days, so 43,830 is the average, not any particular month.
How many minutes are in a year?
525,960 minutes. That is the Julian year of 365.25 days, which averages in leap years. A non-leap year is 365 days = 525,600 minutes, 360 minutes less.
Can I convert minutes back to hours or days?
Yes — the converter works both ways. Type a number in either box and the other updates: 1,440 minutes becomes 1 day, 90 minutes becomes 1.50 hours, and 10,080 minutes becomes 1 week.
