timezonefinder

Notice: Looking for maintainers. Reach out if you want to contribute!

This is a python package for looking up the corresponding timezone for given coordinates on earth entirely offline.

It is recommended to install it together with the optional Numba package for increased performance:

Quick Guide:

pip install timezonefinder[numba]

from timezonefinder import timezone_at

tz = timezone_at(lng=13.358, lat=52.5061)  # 'Europe/Berlin'


# For thread safety, increased performance and control, re-use an instance:
from timezonefinder import TimezoneFinder

tf = TimezoneFinder(in_memory=True)  # reuse

query_points = [(13.358, 52.5061), ...]
for lng, lat in query_points:
    tz = tf.timezone_at(lng=lng, lat=lat)  # 'Europe/Berlin'
