What time should I stick the contraceptive patches?

Yesterday I had a day of changing the contraceptive patch at 20 I put it on as usual at 20 but the glue was probably too weak in this patch or for warm days peeled off as soon as I saw that it was 23:23 I put on a new one I tried to glue that all the time it was on the body peeled it off and glued a new one or I have every time every Sunday stick at 20 or 23:23 please answer this is the second month of use patch and it was the first patch applied this month
