Standard Time Patterns

Classes in Yale College and in the Graduate School of Arts and Sciences must follow these standard time patterns to assure, as far as is possible, that each class is taught in a suitable room. Because the supply of classrooms is limited, some classes will need to be assigned to marginal classrooms in time slots where the demand is great. A detailed view of how classrooms are utilized is available on the Faculty of Arts and Sciences room scheduling site.

Seminars

Seminars meet 150 minutes per week in two 75-minute sessions or 110 or 120 minutes per week in one session. Note that all seminars are understood to be limited enrollment (ordinarily fewer than 25 students).

Competition for rooms is especially keen at these times:
     T 9.25–11.15
     MW or TTh 11.35–12.50
     MW or TTh 2.30–3.45
     T or W 1.30–3.20
     M, T, W, or Th 2.30–4.20 or 2.30–4.30

75-minute sessions may meet using any combination of the following days (column on the left) with the following times (column on the right):

MW		9–10.15
MF		11.35–12.50
TTh		1–2.15
WF		2.30–3.45
		4–5.15

110-minute sessions may meet on the following days at any of the following times:

M, T, W, Th, or F		9.25–11.15

120-minute sessions may meet on the following days at either of the following times:

M, T, W, Th, or F		2.30–4.30
		3.30–5.30

Lecture Courses

Lecture courses meet 150 minutes per week in either three 50-minute sessions or two 75-minute sessions. Introductory and intermediate foreign language courses generally meet 250 minutes per week in five 50-minute sessions.

Competition for rooms is especially keen at these times:
MWF 10.30–11.20
MW or TTh 11.35–12.25 or 11.35–12.50

50-minute sessions may meet using any combination of the following days (column on the left) with the following times (column on the right):

MWF		8.20–9.10
MWF, 1 HTBA		9.25–10.15
MW, 1 HTBA		10.30–11.20
MF, 1 HTBA		11.35–12.25
WF, 1 HTBA		1.30–2.20
TTh, 1 HTBA		2.30–3.20
MTWThF		3.30–4.20
		4.30–5.20
HTBA = hour to be announced. This typically represents a 50-minute discussion section.

75-minute sessions may meet on the following days at any of the following times:

MW		9–10.15
MF		11.35–12.50

Lecture courses that meet for two 75-minute sessions may also meet for an additional 50-minute discussion section.

Competition for rooms is especially keen at these times:
     T or W 1.30–2.20
     T or W 2.30–3.20
     F 10.30–11.20

Discussion sections may meet on the following days at any of the following times:
