HRogWageNow has been delivering the weekly index on a 2 week lag every Monday and in the event of a public holiday or a company holiday we have delivered the data the next business day. 

To enable faster delivery of our data, we will be delivering the data every Monday regardless of whether the day falls on a public holiday or company holiday. Our monthly index will be delivered on the second Monday of the month. The updated schedule can be checked from here. 

This policy change will be first applied for the delivery on April 29th (Showa Day) which was initially scheduled for the following business day on April 30th.
