Timing of Service for Notice of Motion and Oppositions
With 16-7-1.
Assuming personal service
Add 16 to May 1st to get the return date: May 17th. Then subtract 7 from May 17th to find the due
date for oppositions: May 10th. Lastly, subtract 1 from May 17th to find the due date for the
reply: May 16th.
Thus: May 1st (today’s date)  May 10th (due date for oppositions)  May 16th (due date for
reply to oppositions)  May 17th (return date)
Assuming regular mail service
With regular mail service, add five days to 16, thus getting 21. Then add 21 to May 1st, thus
getting May 22nd, the return date. Then subtract 7 from May 22nd and get May 15th, the due date
for oppositions. Finally, subtract 1 from May 22nd and find the due date for the reply: May 21st.
The modified locker combination is as follows: 16(+5) – 7 – 1  21 – 7 – 1
Thus: May 1st (today’s date)  May 15th (due date for oppositions)  May 21st (due date for
reply to oppositions)  May 22nd (return date)
Assuming overnight mail service
With overnight mail service, add 1 day to 16 and get 17. Then add 17 to May 1st and obtain the
return date, May 18th. Then subtract 7 from May 18th and get the opposition due date, May 11th.
Afterward, subtract 1 from May 18th to get May 17th, the due date for a reply to oppositions.
The modified locker combination: 16(+1) – 7 – 1  17 – 7- 1
Thus: May 1st (today’s date)  May 11th (due date for oppositions)  May 17th (due date for
reply to oppositions)  May 18th (return date)
With 8-2.
Assuming personal service
Add 8 to May 1st and get May 9th, the return date. Then subtract 2 from May 9th to get the
opposition due date, May 7th.
Thus: May 1st (today’s date)  May 7th (due date for oppositions)  May 9th (return date)
Assuming regular mail service
With regular mail service, add five days to 8 and get 13. Then add 13 to May 1st and get May
14th, the return date. Afterward, subtract 2 from May 14th to get May 12th, the due date for
oppositions.
The modified locker combination formula: 8(+5) - 2  13 – 2.

2. 2
Thus: May 1st (today’s date)  May 12th (due date for oppositions)  May 14th (return date)
Assuming overnight mail service
With overnight mail service, add one day to 8 and get 9. Then add 9 to May 1st and get May 10th,
the return date. Afterward, subtract 2 from May 10th to get May 8th, the due date for oppositions.
The modified locker combination: 8(+1) – 2  9- 2.
May 1st (today’s date)  May 8th (due date for oppositions)  May 10th (return date)
Timing of Service for Notice of Motion and Cross-Motion
With 16-7-1
Assuming personal service for the notice of motion and cross-motion.
Add 16 to May 1st and get May 17th, the return date. Then subtract 7 from May 17th to get the
cross-motion due date, May 10th. Finally, subtract 1 from May 17th to get May 16th, the due date
for the reply to the cross-motion.
Thus: May 1st (today’s date)  May 10th (due date for cross-motion)  May 16th (due date for
reply to oppositions)  May 17th (return date)
Assuming regular mail service for the notice of motion as well as the cross-motion.
In terms of serving the notice of motion by regular mail, add 5 to 16 to get 21. Add 21 to May 1st
to get May 22nd, the return date. Now move on to the second digit in the locker combination, 7,
and add 3 days for serving a cross-motion by regular mail in order to get 10. Then subtract 10
from May 22nd, the return date, and get May 12th, the cross-motion due date. Then subtract 1
from May 22nd, get May 21st, the due date for the reply to the cross-motion,
The revised locker combination: 16(+5) – 7 (+3) – 1  21 – 10 – 1
Thus: May 1st (today’s date)  May 12th (due date for cross-motion)  May 21st (due date for
reply to cross-motion)  May 22nd (return date)
Assuming overnight mail service for the notice of motion as well as the cross-motion.
In terms of serving the notice of motion by overnight mail, add 1 to 16 to get 17. Add 17 to May
1st to get May 18th, the return date. Now move on to the second digit in the locker combination,
7, and add 1 day for serving a cross-motion by overnight mail in order to get 8. Then subtract 8
from May 18th, the return date, and get May 10th, the cross-motion due date. Then subtract 1
from May 18th, and get May 17th, the due date for the reply to the cross-motion.
The revised locker combination: 16(+1) – 7 (+1) – 1  17 – 8 – 1
Thus: May 1st (today’s date)  May 10th (due date for cross-motion)  May 17th (due date for
reply to cross-motion)  May 18th (return date)

3. 3
With 8-3
Assuming personal service for both.
Add 8 to May 1st to get May 9th, the return date. Then subtract 3 from May 9th to get May 6th, the
cross-motion due date.
Thus: May 1st (today’s date)  May 6th (due date for cross-motion)  May 9th (return date)
Assuming regular mail service for the notice of motion as well as the cross-motion
For the notice of motion, add 5 days to 8 for regular mail service and get 13. Then add 13 to May
1st to get May 14th, the return date. For the cross-motion, add 3 days to 3 to get 6. Then subtract 6
from the return date, May 14th, to get May 8th, the cross-motion due date.
The revised locker combination: 8(+5) – 3 (+3)  13 - 6
Thus: May 1st (today’s date)  May 8th (due date for cross-motion)  May 14th (return date)
Assuming overnight mail service for the notice of motion as well as the cross-motion.
For the notice of motion, add 1 day to 8 for overnight mail service and get 9. Then add 9 to May
1st to get May 10th, the return date. For the cross-motion, also served by overnight mail, add 1
day to 3 to get 4. Then subtract 4 from the return date, May 10th, to get May 6th, the cross-motion
due date.
The revised locker combination: 8(+1) – 3 (+1)  9 - 4
Thus: May 1st (today’s date)  May 6th (due date for cross-motion)  May 10th (return date)
