Labor Day email calendar.
Labor Day falls on the first Monday of September and marks the end of the summer season for many US shoppers. Use it for an end of season edit, send across the weekend with a firm Monday end, and plan the autumn launch email for the week after.
Key dates (US)
- 2026: Monday 7 September
- 2027: Monday 6 September
Last reviewed 12 October 2026. Dates are calculated from the rule for the day, so they stay correct each year.
Why it matters.
The weekend works well for clearing summer stock and for introducing early autumn lines, but the shared sale environment means plain discounts blur together. A clear reason, such as season end or limited stock, tends to hold attention.
It also sits just before the autumn rush, so use the data from it to size your list for Black Friday and to find who is engaged before the loud period begins.
