| Task 2 | 2026-08-31 | 1 week | 2026-09-07 | 2 | Due within 7 days |
| Task 3 | 2025-11-30 | 12 months | 2026-11-30 | 86 | On track |

Formula and limits
Next due = last done + interval. Month intervals keep the same day of the month and fall back to the last day when it does not exist, including leap years. Days left = next due − today. Overdue below 0 days; due soon from 0 to 7.
2026-06-01 + 3 months = 2026-09-01; 2026-09-01 − 2026-09-05 = -4 2026-08-31 + 1 week = 2026-09-07; 2026-09-07 − 2026-09-05 = 2 2025-11-30 + 12 months = 2026-11-30; 2026-11-30 − 2026-09-05 = 86
