Help, needing to mak a clock and activate a led with esp8266 and wemos d1mini

hello everyone i got a topic today, i´m needing to show a clock on a oled display with a wemos d1 mini. Also i have to activate a led when the hour is for example at 6pm. I have problem with that. Someone have any idea how to program all this at the same time? Hope you can help me thank you all.

What have you programmed so far ? A clock with output to the Serial monitor perhaps
