Claim one 30-minute slot and pray in it every week for three weeks. When a slot is taken it is removed, so no hour goes uncovered.
Pick a day and time once. That same slot is yours for all three weeks.
Pray on your weekday at your time — three times over the 21 days.
Once a slot is claimed it disappears, so every half hour is covered in prayer.
