        Events are generated in the range of the input
        [`EventSet`][temporian.EventSet] independently for each index.

        The usability is inspired in the crontab format, where arguments can
        take a value of `'*'` to tick at all values, or a fixed integer to
        tick only at that precise value.

        Non-specified values (`None`), are set to `'*'` if a finer
        resolution argument is specified, or fixed to the first valid value if
        a lower resolution is specified. For example, setting only
        `tick_calendar(hour='*')`
        is equivalent to:
        `tick_calendar(second=0, minute=0, hour='*', mday='*', month='*')`
        , resulting in one tick at every exact hour of every day/month/year in
        the input guide range.
