Version 2.21.0 fails to validate YYYY-10-DD date format

[oalsaab]

When trying to compile or validate a valid ISO 8601 date in the month of October, fastjsonschema returns a JsonSchemaValueException.

>>> fastjsonschema.compile({'$schema': 'http://json-schema.org/draft-07/schema', 'format': 'date'})('2018-10-05')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 6, in validate
fastjsonschema.exceptions.JsonSchemaValueException: data must be date

The issue was most likely caused here:

python-fastjsonschema/fastjsonschema/draft07.py

Line 6 in 524b9e8

'date': r'^(?P<year>\d{4})-(?P<month>(0[1-9]|1[1-2]))-(?P<day>(0[1-9]|[12]\d|3[01]))\Z',

To match October correctly it should probably be (?P<month>(0[1-9]|1[0-2])) for the month regex part.
