Question about 390 days on jobseekers benefit

Hi, just a quick query if anyone can help.

If you're entitled to Jobseekers benefit for 390 days, does that mean 390 calender days(i.e 55 weeks in total) or 390 working days(78 weeks in total)

Thanks.

The SW week is 6 days (mon - sat) so it is 65 weeks.

thanks for that.
