FAQ
Does it account for leap years?
Yes. The calculator measures the true number of calendar days between the entered date and January 1 of the following year, so leap days are included automatically.
Can I enter past years?
Yes. Any valid date in the proleptic Gregorian calendar works, whether it is in the past or future.
What if it's New Year's Day?
The result shows the length of the new year: 365 days for a common year or 366 days for a leap year.
Why use UTC?
UTC avoids daylight-saving and time-zone offsets, so two people in different regions get identical day counts.
Can I calculate the hours instead of days?
Multiply the day result by 24 to convert it to hours, or by 1,440 to convert to minutes.
Additional Information
- The calculation uses UTC to avoid time-zone shifts affecting the number of days.
- Leap years (every 4 years except centuries not divisible by 400) add one extra day to the total.
- If the entered date is already January 1, the result equals the total length of that year (365 or 366 days).
- Negative results are prevented; invalid dates return no result so you can correct the input.
