If you are creating a schedule for a 6 team division over 10 weeks and want to schedule 3 matches every Monday night at 7pm, 8pm and 9pm then you have three options.
1/ Use the template scheduler
When you create timeslots using the template scheduler you can define the number of matches that can play in each timeslot. You would create repeating timeslots for Monday at 7, 8 and 9. Max 1 match per timeslot
2/ Manually make adjustments to an existing schedule
If you already have a schedule but want to stagger some of the matches then you can make manual adjustments afterwards using the MASS UPDATE.
This program allows you to change times of selected matches e.g. from 7pm to 8pm or adjust the dates of matches by adding or removing a number of days e.g. -7 will bring forward selected matches by 1 week.
3/ Use the advanced scheduler
If you are using the advanced scheduler then create 30 timeslots over the 10 weeks. 3 timeslots per night at 7pm, 8pm and 9pm.
Check that the teams are all using the same venue by clicking on MANAGE from ADMIN HOME
The advanced scheduler will never double book a venue or a team so when scheduling a match to play in a week if the the venue isn't available for 7pm it will check for 8pm and 9pm.
