Hello There
i am using https://github.com/STMicroelectronics/STM32CubeWL/tree/main/Projects/NUCLEO-WL55JC/Applications/LoRaWAN/LoRaWAN_End_Node_FreeRTOS this example ,
in that there is timer used for sent the data , i want RTC for send data for particular time and all how can i do ???

I would start by looking at examples to use the RTC.
Get one/some of them working to understand the RTC.
Also read the Reference Manual section on the RTC.
See also Application Note AN4759, "Introduction to using the hardware real-time clock (RTC) and the tamper management unit (TAMP) with STM32 MCUs"

in the example of FreeRTOS_End_Node i am unable to initialize RTC if you provide me example for that its very good for me

Before trying to add it to some other project, have you got it working in a simple, standalone example?
Always best to start simple to gain understanding.
Once you've got that, you'll have a working example for reference ...

Actually in Lorawan_end_Node_freertos example the RTC is conflicting with UTIL TImer so
Standalone works

So what is the conflict?
