Conversion number between year (Julian) [a, y, or yr] and year (mean tropical) [a, y, or yr] is 1.0000213819712. This means, that year (Julian) is bigger unit than year (mean tropical).
Switch to reverse conversion:
from year (mean tropical) to year (Julian) conversion
| [a, y, or yr] |
Result in year (mean tropical)
?If conversion between year (Julian) to second and second to year (mean tropical) is exactly definied, high precision conversion from year (Julian) to year (mean tropical) is enabled.
Since definition contain rounded number(s) too, there is no sense for high precision calculation, but if you want, you can enable it. Keep in mind, that converted number will be inaccurate due this rounding error!

Definition of year (Julian) unit: = 365.25 d average. The basic calendar year has 365 days, but in fact the Earth needs a little more time around the sun. The Julian calendar compensated this with leap year (every fourth year had 366 days). According to the formula, a Julian year has 365 + 1/4 = 365.25 days. But even with this compensation, the astronomical year slip 0.78 days every 100 years into real seasons. Therefore, most countries have moved to the Gregorian calendar introduced in 1582.
Definition of year (mean tropical) unit: ≈ 365.242190402 d. Tropical year is the length of time it takes for the Sun to return to the same position in the cycle of seasons, approximately 365.24219 days
