How the deadline works

Under Cal. Civ. Proc. Code § 437c(a), as amended effective January 1, 2025, the motion must be served at least 81 days before the hearing, the opposition is due at least 20 days before the hearing, and the reply at least 11 days before. These summary-judgment periods are counted in CALENDAR days (unlike general law-and-motion under § 1005, which uses court days). This calculator counts 20 calendar days backward from the hearing and rolls a weekend/holiday landing to the prior business day so the full notice is preserved.

  • Calendar days (not court days) Summary-judgment timing under § 437c runs on calendar days, unlike § 1005 motions.
  • 2025 amendment The periods rose to 81/20/11 days effective January 1, 2025 (from 75/14/5).
