80 hours in 14 days, which is about 40 hours a week.

Which Friday is off?

In HoursPad's preset the second Friday is off. Employers choose their own, so move the 8-hour day and the day off in the "Pattern" box if yours are the other way round.

How many work days fall in 2027?

234 from the example start date to the end of 2027.

Is this the official 9/80 schedule?

No. HoursPad shows a pattern and repeats it. Your employer's schedule or union agreement decides the real one. Change the "Pattern" box to match yours.
