the.com/day of reckoning

means The moment when consequences you've postponed finally catch up and have to be paid in full.

from From 'reckoning,' meaning a calculation or settling of accounts — rooted in Old English 'gerecenian,' to explain or recount. The phrase draws its weight from religious tradition, especially the Christian notion of a final Day of Judgment when every soul's ledger is totaled and read aloud. Over time it slid from theology into everyday speech, keeping the courtroom hush but losing the requirement of an actual afterlife.
