I don't know the future, but I expect Satan-Putin of Russia to begin some forceful acts next year 2018-August-20 or July-06, I calculate this from knowing the book of Daniel. Yes, it's interesting. The calculation is:
(Pick a Day) + 2300 days - 1290 days + (0 days or - 45 days).

CORRECTION: We are still waiting for Daniel 11:31 to BEGIN (therefore, possibly including Daniel 11:29-31). Therefore, the formula I stated using "- 1290 days" is now theorized to be "+ 1290 days" in the formula:

"Pick a Day + 2300 days + 1290 days + (0 days or 45 days)."

This formula (calculation) change to "+ 1290 days" (away from "- 1290 days" [note the change to PLUS (+)] would mean that Daniel 9:27 (quoted next) actually means "for" within the phrase "... ["for" (changed away from "in the"] midst [of] seven...."

Daniel 9:27 is quoted next.

Daniel 9:27a "And he shall confirm [H1396] the covenant [H1285] with many [H7227] for one [H259] week [H7620 "seven"]: and in the [should say "for"] midst [H2677] of the week [H7620 "seven"] he shall cause the sacrifice [H2077] and the oblation [H4503] to cease [H7673], ..."

Continued, Daniel 9:27b "...and for the overspreading [H3671] of abominations [H8251] he shall make it desolate [H8074], even until the consummation, [H3617] and that determined [H2782] shall be poured [H5413] upon the desolate [H8074]."

In Daniel 9:27, to "confirm the covenant for a seven" means "2300-evening-mornings" (days) in Daniel 8:14, since 2300 days equals 6.301 years which the 2300th day spans into the "seventh" year ("seven" in Daniel 9:27).

Also, "midst of seven" in Daniel 9:27 means to add (+) 1290.

That is, "[for] midst of seven" in Daniel 9:27 means to add (+) 1290 days to 2300 days.

Therefore, if 2300-evening-mornings (days) in Daniel 8:14 BEGAN circa 2015-August-16 or 30-September-2015, then add "2300 days" to end on 02-December-2021 or 16-January-2022. Now add 1290...

Now add 1290 days (in Daniel 12:11) to the 2300 days (in Daniel 8:14). Therefore, add 1290 days to 02-December-2021 or 16-January-2022, to result in 1290 days ending circa 14-June-2025 or 29-July-2025 (that's during the "summer" in the northern hemisphere where the great USA is).

The THEORIZED dates ending circa 14-June-2025 or 29-July-2025 (that's during the "summer" in the northern hemisphere where the great USA is) could vary by 45 days (consider Daniel 12:12 where 1335 days is 45 days after 1290 days). That's when Jesus returns to save us BELIEVERS.

ANOTHER POSSIBLE DATE (Nobody knows exactly) FOR RUSSIA (Satan-Putin) to BEGIN Daniel 11:31 (Daniel 12:11 for 1290 days) "could" be in 14 days (on 04-June-2019) from today (21-May-2019) which is 2300 days (Daniel 8:13) after the 15-Feb-2013 Chelyabinsk meteor fell in Russia....

The 15-Feb-2013 Chelyabinsk meteor that fell to earth in Russia is either metaphorically or literally Satan being again cast to earth, to maybe (we don't know) have BEGUN 2300 days (Daniel 8:13) which would END soon 04-June-2019 which BEGINS 1290 days (Daniel 11:31, 12:11)...

"If" the 1290 days BEGINS on 04-June-2019 with Satan-Putin "taking-away continually" in Daniel 11:31 & Daniel 12:11, then that 1290 days would END circa 15-December-2022 or 29-January-2023 (adding 45 days due to Daniel 12:12 stating 1335 days which adds 45 days to 1290 days).

The coming date of 04-June-2019 -- is 14 days from today 21-May-2019 -- has more significance due to the following report titled "NORAD Jets Intercept Russian Bombers, Fighters Off Alaska

If Russia (Satan/Putin) on 04-June-2019 BEGINS "taking-away continually" in Daniel 11:31 & 12:11 for 1290 days, then... the web link below is the VIDEO of the Chelyabinsk meteor that fell from the sky to the earth ("from heaven to earth") on 15-Feb-2013: https://twitter.com/biblereadingmm/status/932149280466395136?s=21
