LinkedIn publishes no daily connection limit. Its help page on invitation restrictions says every member has an invitation limit and that sending many invitations within a short amount of time can stop you sending more. It gives no count for the day and no length for "short". The daily figures you find elsewhere are estimates that LinkedIn has not confirmed.
So the useful answer is a pace, not a ceiling. The planner above opens on the day.
How to read the daily pace
The planner works out a weekly plan from your answers, then splits it over the working days, rounded down. Read the result as the most to send on one day, spread through that day. It is not a quota to reach. When the week is too small to split, the planner says how many days to send on instead.
A recent limit notice puts a pause first, with LinkedIn's own wait. The pace underneath is for when you start again.
How to shape the day
LinkedIn's "short amount of time" is about pace, so the shape of the day matters more than the total:
Send through the day, not all in one sitting.
Let a skipped day go. Doubling up the next morning is the same burst, one day later.
Keep the plan after a quiet week. Nothing happening is not proof of a higher limit.
Invite people likely to know you. Invitations that are ignored or left pending count against you too.
If a notice does arrive, stop. When the LinkedIn connection limit resets has LinkedIn's wait for each case.
Daily limits in Oneprofile
In Oneprofile, every LinkedIn action has a daily limit you set for each sender. When it is full, the next step waits until midnight in the sender's time zone. A wait between steps and the sequence's sending hours spread the rest through the day.
The Chrome extension is a companion: it does each step in your own browser, the one you would otherwise click through yourself. A newly connected sender starts with every step waiting for your approval.
