Conversion number between Planck time and year (Gregorian) [a, y, or yr] is 1.7083905948838 × 10-51. This means, that Planck time is smaller unit than year (Gregorian).
Switch to reverse conversion:
from year (Gregorian) to Planck time conversion
| Planck time |
Result in year (Gregorian)
?If conversion between Planck time to second and second to year (Gregorian) is exactly definied, high precision conversion from Planck time to year (Gregorian) 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 Planck time unit: ≡ ( Gℏ⁄c5) 1⁄2. It is the time required for light to travel in a vacuum a distance of 1 Planck length, approximately 5.39 × 10−44 s.
Definition of year (Gregorian) unit: = 365.2425 d average. As the common year has 365 days, the Gregorian calendar with leap years compensate the deviation from the real, astronomical year. According to this calendar, every 4th year is a leap year, except for every 100th. But every 400th is a leap year. This means that there are 97 leap years in 400 year period. So according to Gregorian's calendar, one year has 365 + 97/400 days (average). This is not a perfect approach, but in 1000 year period, the defiation is only 0.3 days compared to the astronomical year. In the year 1582 Gregorian replaced the Julian calendar.
