How to track calendar with RTC in STM32F103CB?

[kadir ustun1]

Hello everyone,

I want to do not change date, When I load a new program to STM32F103. How can I do these ?

Thank you

This is a recurring question; I assume you are using Cube/HAL which appears to have a wrecked way to keep date.

See for example https://community.st.com/s/question/0D50X00009XkekSSAR/stm32f103-rtc-vbat-date-resets-after-power-off and search this forum for "STM32F103 RTC date".
