Record a birthday and Longtime keeps it in view — on the person, in your People list, on the dashboard as it goes by, and on your own calendar if you like.

A birthday is the easiest reason to get in touch, and the easiest one to let slip by. Longtime keeps them where you will see them, and makes the follow-through one tap.

Recording a birthday

Mention it in the interview — "Sam's birthday is March 3rd" — or add it when you edit their details on the person's page. If you know the year, Longtime shows their age too. vCard and other imports bring birthdays in with everything else.

Where birthdays show up

On the person — their page and card show "Birthday in 12 days" when it is within a month, and "Birthday today" on the day.
In People — the quick filters for upcoming and recent birthdays gather them, and you can sort by upcoming birthday.
On the dashboard — once a birthday has arrived, it waits in the Birthdays panel for up to a week until you deal with it.
On your calendar — add a Birthdays calendar to Google, Apple or Outlook Calendar that keeps itself up to date. See Constant Bridges.

Did you send birthday wishes?

When a birthday arrives, Longtime asks — on the dashboard, on their card in People and on their page — "Did you send birthday wishes?"

Answer yes, then say how: by text, email, phone or in person. That logs a connection of that kind with them straight away (phone counts as a voice call, in person as a one-on-one), so it counts toward their cadence.
Answer no, then say you are planning to — it stays on the dashboard until a week after their birthday — or skip it this year, which sets it aside until next year.

The dashboard is the reminder

Longtime does not email you about birthdays. Check the dashboard, or publish a birthdays feed (see Constant Bridges) so they appear on the calendar you already look at.

Someone who has died

Add a date of death in the interview and Longtime remembers them that way: their page shows the dates of their life instead of an age, the main button on their page offers to update them rather than asking what is new, the panel about where you stand with them goes away, they no longer come up as due in Reconnect, and Longtime stops asking whether you sent birthday wishes. Their birthday still appears in a published birthdays feed, as an all-day event on the date.
