Hello 
I have habit rows…
i compute if the streak is succeed (at present time)
I managed to do it for daily habits with
=> IF “current day” is within maths: “LASTLY DONE DATE” + 24H = STREAK IS TRUE (currently succeed/not failed yet)
User will want to do it at different frequency…
#daily habits 
#- specific days of the week habits (monday yes, tusday no, wednesday no, thursday yes …): 
FYI:
i know how to use (found the topic 
):
→ the weekday(day) math function. to get the day if the week number(1,2,3,4,5,6,7)
→ easier option as David recommended: Glide • Format Date column
I have a feeling it’s more of a math game than logic… but i’m below average in Maths ><
In a nutsheel
How to create a system of columns, inside a row, to have habits automatically marked as CURRENT/DONE/FAILED according to specific days of the week? (customised by user)
Thanks in advance
