As we all know, the Facebook Hacker Cup 2021 — Round 1 is being held from Saturday, September 11, 2021, 10:30 PM (IST), till Sunday, September 12, 2021, 10:30 PM (IST). The timing for Codeforces Global Round 16 is from Sunday, September 12, 2021, 8:05 PM (IST) and will last 150 minutes. These 150 minutes will clash with the Facebook Hacker Cup, so I humbly request you postpone the Global Round 16 by 24 hours.
