And I beheld when he had opened the sixth seal, and, lo, there was a great earthquake; and the sun became black as sackcloth of hair, and the moon became as blood; Revelation 6:12

The following is 2 different versions of Revelation 6:13. The "untimely figs" or "winter fruit" could be a clue pointing to when the 6th Seal will be opened:

King James Bible
And the stars of heaven fell unto the earth, even as a fig tree casteth her untimely figs, when she is shaken of a mighty wind.

English Standard Version
and the stars of the sky fell to the earth as the fig tree sheds its winter fruit when shaken by a gale.

If "untimely figs" happen during the winter or early spring, it could mean the rapture happens right before or simultaneously with it. After Seal 6 is broken, I think the "business as usual" life described as in the days of Noah wouldn't apply. The world would rapidly fall apart. The Bible says the stars of heaven are going to fall so I'm wondering if that will be a comet/s that hasn't been discovered yet or even possibly a broken up comet like Ison's and or its debris tail. Interesting times.

The fig-tree of Israel (Ficus carica) produces two and sometimes three crops of figs in a year, (1) the bikkurah, or “early-ripe fig” (Micah 7:1; Isa. 28:4; Hos. 9:10, Revised Version), which is ripe about the end of June, dropping off as soon as it is ripe (Nahum 3:12); (2) the kermus, or “summer fig,” then begins to be formed, and is ripe about August; and (3) the pag (plural “green figs,” Song of Songs 2:13; Greek: olynthos, Rev. 6:13, “the untimely fig”), or “winter fig,” which ripens in sheltered spots in spring.
