Why is it still saying that I'm missing "day" field?

I'm trying to use os.time for my game, but it keeps saying that I'm missing the "day" field in the date table.

local year = 2018
local month = 12
local day = 23

local date = {year, month, day}

while true do
	print(os.time(date))
	wait(1)
end

I was pretty sure I included the "day" value in it, but it's saying that it's missing. Does anyone know how to get this to work?

I had to look here. Looks like the table is meant to be a dictionary like {year=x,month=x,day=x}. So this should work...

local year = 2018
local month = 12
local day = 23

local date = {year=year, month=month, day=day}

while true do
    print(os.time(date))
    wait(1)
end
