Counting days until threshold reached

I am not sure that I understand correctly:

Is it properly marked (in post you've said 'what is the date')

	A	B	C	D	E	F	G
1	Plant	date	rain	TEMP	200	300	400
2	A	01/01/2018	0.50	8.0
3	A	02/01/2018	2.20	2.0
4	A	03/01/2018	1.10	9.0
5	A	04/01/2018	0.25	55.0
6	A	05/01/2018	0.33	4.0
7	A	06/01/2018	2.20	15.0
8	A	07/01/2018	1.10	23.0
9	A	08/01/2018	2.20	32.0
10	A	09/01/2018	1.10	31.4
11	A	10/01/2018	2.20	34.2	X
12	A	11/01/2018	1.10	37.1
13	A	12/01/2018	0.25	39.9
14	A	13/01/2018	4.30	42.8		X
15	A	14/01/2018	2.23	45.6
16	A	15/01/2018	2.35	48.5			X
17	A	16/01/2018	2.46	51.4
18	A	17/01/2018	2.57	54.2
19	A	18/01/2018	2.68	57.1
20	A	19/01/2018	2.80	59.9
21	A	20/01/2018	2.91	62.8
22	A	21/01/2018	3.02	65.6
23	A	22/01/2018	3.13	68.5

or you want to know how many days passed (as in thread title is 'counting') from 'initial date' in particular date like:

	A	B	C	D	E	F	G
10	A	09/01/2018	1.10	31.4
11	A	10/01/2018	2.20	34.2	9
12	A	11/01/2018	1.10	37.1
13	A	12/01/2018	0.25	39.9
14	A	13/01/2018	4.30	42.8		12
15	A	14/01/2018	2.23	45.6
16	A	15/01/2018	2.35	48.5			14

I am a bit confused myself as to whether the request is for the date or the number of days, so I put dates in columns E:G and number of days in columns I:K.
Column H is a helper column populated using: =SUMIFS(D$2:D2,A$2:A2,A2)
Columns E:G are populated using:

Columns I:K are populated using: =IF(E2="N/A","N/A",E2-$B2)
Let us know if you have any questions.

I think you will need VBA for this, not least because you need a "moving target" of each threshold (200,300,400) for each starting date i.e column H in JeteMc's file repeated 27 times (number of unique dates) _ or have I mis-understood ???

with 118K rows the number dates is going to considerably more than 27!

I need more explanation about what to do on rain and temp? or like 200/300/400-(rain or temp) every day until the end of the list then get the row of the first negative value?

Edit : I try as far as I understand, i am sorry if it doesn't meet the request

I feel that John has come up with the better solution.
However, in the interest of responding to post #5:
If you only want to know the number of days then modify the formula in E2 so that it reads:

If you don't need to see the three thresholds at one time put a drop down in cell E1 with the list 200, 300, 400.
At this point only two columns of calculation, E and H, are needed.
