Hi,

thank you for your solution. It is clever and “automatically” works until 2032 but needs TOO MUCH blocks. It is problem. I think the best solution (with minimum blocks) will be looking for first Thursday in new month and problematic months add separately. In the year 2017 it is September and December. In the beginning of ach year (2018,…) I will have to add new problematic months.

Solution in attachment.

It is little misunderstanding.

I need this function forever (not only for year 2017), but when Logo is partly full now (328 of 400 block) next over 40 blocks is many for me. I know, it is my problem, but I am afraid I will have to add Logo_VI. Therefore I save blocks.

Thanks

Carlos

Hello Ixo,

Like you well posted, a problem occurs when Friday is the first day in any month. These are our "Friday first".

But there is a solution. We can use a yearly timer setting <montly> and <days> 1 to 7. Also, we need add "Exceptions": yearly timers for all  "Friday first" (2017 will have 2, 2018 will have 1, 2019 will have 3…).

The good new is: when Friday is the first day in any month, the next Friday will be 8. Then, Thursday will be 7. So, the yearly timer setting <montly> and <days> 1 to 7 goes to "0" state at this day. That means there is no duplicity in a month with "Friday first".

I think to be right.

I did not see your solution. It can be better than this one.

Regards,
