About Converting Days to Minutes
Days and Minutes are both everyday units of duration, and converting between them is one of the most routine calculations there is — scheduling, project planning, and billing all depend on it. Days is most often used for calendars and scheduling worldwide.
Formula
minutes = days × 1440
This factor comes from each unit's defined relationship to the category's base unit: 1 days equals 86400 base units, and 1 minutes equals 60 base units, so dividing one by the other gives the direct days-to-minutes factor of 1440.
Simple example
1 d × 1440 = 1,440 min
1 days = 1,440 minutes.
Real-world example
24 d × 1440 = 34,560 min
24 days = 34,560 minutes.

History of the Days
The day as a natural unit (one Earth rotation) is prehistoric in origin; its fixed 86,400-second definition follows from the standardized hour, minute, and second, decoupling the calendar day slightly from the actual (very gradually lengthening) astronomical day.
Historical origin. Days was not the invention of a single named person; it developed through the process described above.
Understanding the Minutes
Minutes (min) measures time. A minute is 60 seconds, part of the base-60 (sexagesimal) time-division system inherited from Babylonian astronomy. It is classified as a Non-SI unit accepted for use with SI.

Uses of the Minutes today
- Everyday scheduling and timekeeping
- Cooking and recipe timing
- Sports and event timing
History of the Minutes
Like the second, the minute derives from the ancient Babylonian sexagesimal division of the hour, standardized into modern timekeeping without a single inventor.
