if any one can remind me when the 40 day period after giving birth finishes, do you do ghusl on the 40th day or on the 41st day?
and how do you work out the exact 40 days?
i should remember this from last time but i don’t 
*she was born at 2.30 in the afternoon on the 19th May. *
i cant figure out the exact 40 days it’s somewhere between 27th june and 29th June.

*As far as i know these 40 days, physical interaction between husband wife is not allowed, once the time period is up then you do ghusl and can interact with husband *
Re: Ghusl 40 days after childbirth
i didn’t know it had to be exact.
i’ve heard you can read namaaz when you stop bleeding.
You dont just calculate it by counting days, you have to look at your postpartum bleeding [nifas]. If your bleeding stops before 40 days, then you do ghusl at that point, and can resume your prayers, intimacy etc, you dont have to wait for 40 days
More details:
You can read namaaz if you stop bleeding before 40 days so it means you can do ghusl too.
Re: Ghusl 40 days after childbirth
The 40 days is a cultural thing not religious, As mentioned above if you have stopped bleeding you can do ghusl and resume as normal.
Congrats by the way! Hope all is going well!
