SUMMARY:ALL JA Contest
DESCRIPTION:Sponsor: JARL\nModes: CW\, SSB\, FM (AM)\nBands: 160m\, 80m\, 4
 0m\, 20m\, 15m\, 10m\, 6m\nBand note: 1.9\, 3.5\, 7\, 14\, 21\, 28 and 50 
 MHz. The phone all-band category excludes 14 MHz\; CW may use it. JARL's 
 電話 covers AM\, SSB and FM\, and 電信 is CW.\nDuration: 24h\nExchange
 : RST\, the prefecture or region number for where you are operating\, and 
 one letter for power -- H above 100 W\, M to 100 W\, L to 10 W (20 W on 50
  MHz)\, P at 5 W or less. Tokyo at 10 watts on phone sends 5910L.\nEligibi
 lity: Entry limited to JA. K stations may be worked but cannot submit an e
 ntry.\nNote: The rule is anchored on the LAST SUNDAY and counts backwards 
 to the Saturday\, which is how JARL writes it. Checked rather than assumed
 : that is the same date as 'the last full weekend of April' in every year\
 , and always will be -- April's last Sunday falls on the 24th at the earli
 est\, so the Saturday before it is never outside the month. JARL's wording
  is encoded because it is JARL's\, not because it changes an answer. Contr
 ast ACAG\, where the equivalent choice moves the contest a full week in 20
 28 and 2029. Encoded as wall_clock in Asia/Tokyo because that is how JARL 
 states it -- 21時00分（JST） -- rather than converted to a fixed UTC t
 ime by hand. Japan has not observed daylight saving since 1952\, so the tw
 o are identical in practice and will stay so\; the record says what the sp
 onsor said and lets the engine do the arithmetic. log_deadline_days is abs
 ent. JARL prints a dated deadline above the rules for the edition in hand 
 -- ALL JA 2026 is '提出締切日 2026年5月6日（水）必着' -- and 
 the numbered 規約 clauses that follow state the dates\, eligibility\, ba
 nds\, categories and exchange but no submission span. All four of JARL's 2
 026 deadlines happen to fall exactly ten days after their contest ends\, w
 hich is suggestive and is not a rule JARL wrote. The same reasoning alread
 y keeps a deadline off JARL's All Asian records.\nRules: https://www.jarl.
