Real-time clock M41T62 per day leave for 6 minutes henceforth. I found out that the quartz frequency is about 32.9 kHz. Program calibration does not reduce this inaccuracy. Do I have a defective chip or I don’t understand something?

Well you haven't provided a part number for the specific crystal you're trying to use.
Make sure to use the 6-7pF crystals not the more common 9 or 12pF ones

I am using the M41T62LC with integrated crystal. There is one 100nF capacitor between power and ground. Is everything right or am I missing something?

Would suggest you contact your local sales office, and work with the FAE or support engineer there.
