A measurement calendar that respects Thai campaign seasons
Volume drops in mid-April are not always a broken SDK. Sometimes the country is on the road with water and family. Alignment desks that ignore that look careless upstairs.
Global playbooks assume Q4 is the only weather that matters. In Thailand, Songkran, Chinese New Year travel, payday Fridays, and 11.11 each move event mix as much as a media spike. Cross-platform analytics alignment has to calendar those weeks or it will file outage tickets against culture.
What we pin on the wall
The Thailand Market Measurement Cadence short course starts with a printed year. Red weeks are expected volume shocks. Gold weeks are identity shocks — more guest checkout, more new devices, more mini-app traffic from relatives who do not keep the app installed.
During Songkran, iOS and Android do not drop in parallel. Travel-heavy categories lose Android faster if the user is on a relative’s Wi-Fi and a different Google account. SKAN windows still close on Apple’s clock, not on the holiday. Your reconciliation sheet should say “holiday mix” in the notes column, not “possible MMP delay” by default.
11.11 is an identity holiday
Marketplace apps see hybrid checkout explode: browse on web, pay in-app, sometimes finish on a LINE mini-app. That is three dialects of purchase in forty-eight hours. If the treaty does not include a checkout_surface parameter before November, you will celebrate a double count.
Payday Fridays are quieter but more reliable. Subscription trials that start on salary day churn differently from trials that start mid-month. First-party tables know this. MMP dashboards often do not, because they were not asked.
ICT, always
Write Bangkok time on every export filename. Remote seats joining from Singapore still report ICT for studio work. It sounds small until someone diffs a campaign that “ended” at midnight UTC and wonders why Thai spend continued.
The Alignment Atlas treats seasonal weather as a fourth territory, equal to clocks, identity, and dialects. If your desk only has three, add the calendar before the next long weekend.
