Basic date and time types. Implements a subset of the CPython datetime module.

NOTE: This library has a large memory footprint and is intended for hardware such as the SAMD51, ESP32-S2, and nRF52.


This driver depends on:

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

Installing from PyPI

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:

pip3 install adafruit-circuitpython-datetime

To install system-wide (this may be required in some cases):

sudo pip3 install adafruit-circuitpython-datetime

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .venv
source .venv/bin/activate
pip3 install adafruit-circuitpython-datetime

Usage Example

# Example of working with a `datetime` object
# from
from adafruit_datetime import datetime, date, time

# Using datetime.combine()
d = date(2005, 7, 14)
t = time(12, 30)
print(datetime.combine(d, t))

# Using
print("Current time (GMT +1):",

# Using datetime.timetuple() to get tuple of all attributes
dt = datetime(2006, 11, 21, 16, 30)
tt = dt.timetuple()
for it in tt:

print("Today is: ", dt.ctime())

iso_date_string = "2020-04-05T05:04:45.752301"
print("Creating new datetime from ISO Date:", iso_date_string)
isodate = datetime.fromisoformat(iso_date_string)
print("Formatted back out as ISO Date: ", isodate.isoformat())
