Answer: no, not really. Both correlations sit near zero. Meeting titles are classified with a keyword denylist — childcare/family events, personal care, medical appointments, and calendar-blocker titles ("Appointment," "Private," "Dad Mode") are excluded, everything else that reads as a real meeting (interviews, standups, 1:1s, syncs) counts. See the breakdown below for weekday/weekend and busy/light splits.

Split	Days	Avg meeting hrs	Avg stress	Avg sleep score
Weekday	65	2.18h	1.43h	84.7
Weekend	26	0.00h	1.42h	83.5
Busy days (≥3h)	15	—	1.65h	83.0
Light days (<3h)	76	—	1.38h	84.6

Weekdays average 2.2h of real meetings versus essentially none on weekends — a stark gap — yet average stress and sleep score are nearly identical across both. The busiest few days (3h+ of meetings, n=15) do run a little hotter on stress than lighter days, but the sample is small enough that it's more "worth watching" than "proven."
