6). An employer may designate and communicate to the
employer's employees a 12-month period other than the
calendar year, in which case such compensation shall be
provided not later than 31 days after the end of such
12-month period.
12 months + 31 days = 13 months
I think the problem we have here is that I believe that big companies will use what is best for them, and you don't.
That says that the employer does not have to use the calendar year i.e. January to January and they can designate another period such as a fiscal year or something like October to October.
Its not a problem what big companies will use or will not use since both the employee and the employer must agree for this benefit to be available.
`(4) Private employer actions.--An employer that provides
compensatory time under paragraph (1) to employees shall not
directly or indirectly intimidate, threaten, or coerce or
attempt to intimidate, threaten, or coerce any employee for the

time off in lieu of payment of monetary overtime
compensation for overtime hours; or
``(B) requiring any employee to use such
