We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Outdated “current” year
# Bug report

## What's wrong

Some providers return “current” dates from a few years ago, because they are hardwired to the “current” year from those times, such as:

- `mimesis.Datetime().week_date()`
- `mimesis.Datetime().date()`
- `mimesis.Development().version(calver=True)`
- `PolandSpecProvider().pesel()`

## How is that should be

Having a global `now` would break a lot of things, because with the same `seed`, we would get different results at each run.

Then maybe changing mimesis' versioning to calver and do such updates of default year with every major version? This would allow adding methods like `birthdate` to the `Person` provider as well.

## System information

Not relevant.
