now I sat my egg around 12 on the 25th are you counting 25th as one day? I figured lock down Friday the 15th.
I set mine on Saturday the 23rd. The 24th was day 1 for me. That makes today day 18, and Saturday will be day 21. Day 21 is always the same day of the week that you set. If you set on a Monday, your hatch day will be Monday.
