January-March 1s Movies: from mid-April
April-June 1s Movies: from mid-July
July-September 1s Movies: from mid-October
October-December 1s Movies: from mid-January
If you've uploaded at least 10 photos or videos during a season, you should receive your 1s Movie according to the above schedule. Even if you don't upload enough photos/videos during a given season, you can still upload photos/videos later to get your 1s Movie. Please note that you'll only receive Seasonal 1s Movies for 2018 and later.
*With Premium, you'll still receive Seasonal 1s Movies in addition to monthly and yearly ones. Monthly 1s Movies will generally be delivered earlier in the month than your Seasonal 1s Movie.
