.. leading zeros are required for `frontmatter` to treat them as dates
rather than strings, apparently per the YAML specification.
This was done by script:
```py
import re
import datetime
import pathlib
import sys
import frontmatter
rx = re.compile(r'^(\s*)date_added:.*$', re.M)
for path_str in sys.argv[1:]:
print(path_str)
path = pathlib.Path(path_str)
post = frontmatter.load(path)
date_added = post.get("date_added", "")
if isinstance(date_added, datetime.date):
continue
if isinstance(date_added, str):
try:
date_added = datetime.datetime.strptime(date_added, "%Y-%m-%d")
except ValueError as exc:
print(f"Failed to parse date {date_added} in {path_str}: {exc}")
continue
date_added = date_added.date()
content = path.read_text("utf-8")
new_content = rx.sub(lambda m: f"{m.group(1)}date_added: {date_added}", content)
assert content != new_content
path.write_text(new_content, "utf-8")
```

CircuitPython on an ARM Cortex M4 in almost 1 square inch! This "Just Add Solder" castellated module is perfect for incorporating into your own project. The CircuitBrains Deluxe board footprint is small enough to fit into narrow spaces and wearable projects.
NOTE: This board does not have a USB connector for the native USB. Native USB is broken out on the header/castellations and therefore requires a non-standard USB connection such as mounting to a motherboard PCB.
