It is 2:22:22 on 2/22/2022, which happens to also be a Twosday.
This is not the only Twosday which will ever happen on the Gregorian calendar; 2/22/2220 is also on a Twosday. If anyone else is still around in 198 years, they can also have a celebration of numerical assonance.
2/22/2222 is, unfortunately, on a Friday. Pope Gregory XIII clearly failed to think ahead.
Anyway, the real celebration will be in 20 hours, when it’s 22:22:22.
