The TWICE ONCE membership calendar — the windows that repeat every year

The single most useful thing about TWICE's ONCE membership is that it's predictable. Unlike some fandoms where renewal floats with the comeback cycle, ONCE has historically opened its annual membership in a recurring early-year window. Predictable means plannable — and plannable means you never get caught with a lapsed membership the week a tour presale drops.

The recurring shape

ONCE memberships have historically run on an annual cycle opening in early January (recent cycles have used a roughly January 3-24 enrollment window). The exact dates shift a little year to year, but the window — first few weeks of January — has been stable enough to plan around.

Phase	Rough window	What to do
Enrollment opens	Early January	Join / renew here
Enrollment window	~3 weeks	Don't wait for the last day — payment friction happens
Active membership	~1 year from join	Covers presales during the cycle
Gap risk	Late Dec → early Jan	Old cycle ended, new not open — worst time for a surprise presale

The "gap risk" row is the one that bites people: if a year-end surprise event appears before the new January enrollment opens, a membership that expired in December leaves you outside the gate.

Why this matters for tickets, not just perks

The membership isn't really about the welcome kit. It's the presale gate. As the ticket timeline lays out, the fan-club presale is where the good seats actually go — the public sale is the backup. A current ONCE membership in January means you're eligible when a spring/summer tour presale lands; a lapsed one means resale prices.

The plan

• Mark early January as your renewal window, every year, as a recurring reminder. Treat it like a subscription you actively re-up, not one you hope auto-renews.
• Get the verification done immediately after joining — name match and region settings are what actually let you enter a presale, not just hold the badge.
• Keep your payment card consistent with the membership name; name-locked tickets check this later.
