1025

The countdown inside The Tumor.

1025 is the third significant number to make an appearance in Homestuck. It is the result of adding 413 to 612 and thus is symbolic of the interconnection between the kids' and the trolls' sessions, as well as the Green Sun.

Appearances as a Time

• Jade's countdown, instead of being a variation of 413 like the other kids, is 10:25 instead. This connects to Jade's Guardian, Becquerel, also being a first guardian, and Jade's eventual merge with him. Jade also notes how these kinds of numbers are often significant.
• A timer begins counting down when Jack Noir appears in the trolls' session which starts at 10:25 when he slices the door to the kids' universe.
• Karkat wakes from dreaming at 5:12:30 according to the timer. 5:12:30 is half of 10:25:00.
• The Tumor contains a counter inside the center dot that starts at 10:25 when first seen.

Appearances as a Date

• In Hiveswap one of Joey's diary entries is dated 10/25/1994, in the entry she laments her return to school and is surprised that she hadn't made a diary entry since the beginning of the school break on 6/12.
