| eval prevWeekDate=strftime((now(),"-7d"),"%Y/%m/%d")
| table prevWeekDate
Ah, this requires a trick or two. You can't really put the date in a heading, but you could create a single value panel at the top of the dashboard, and this single value panel could contain the following search:
index=main | head 1 | eval month_year=strftime(now(),"%B %Y") | table month_year
Actually, I'll bet that you can put the data in a heading, if you write some javascript etc. I think the above method is pretty simple.
Thanks for that. I'll try it out.
