## What is Longitude°?

Longitude° is a calendar for people whose days cross time zones.

Switch the whole calendar to another time zone in one tap. Every event moves to the correct local time while the underlying moment stays unchanged. Or open Dual Time to read the same day against two local clocks at once—without duplicating or changing a single event.

Highlights:

• One-tap time-zone switching across your entire calendar
• Dual Time: one schedule with two time scales, dates, and all-day lanes
• Month, Week, 3-Day, Day, and chronological Schedule views
• Daylight-saving-aware time conversion
• Connected multi-day bands in a fixed six-row Month view
• Search across the calendars you choose to display
• Create and edit events, recurring series, reminders, colors, guests, RSVP, availability, rooms, attachments, locations, links, and supported meetings
• Optional direct connections to Google Calendar and Microsoft 365
• Light, Dark, and device-default themes with coordinated color palettes
• Local-first design with no Longitude° account, ads, tracking, or Longitude°-operated analytics service

Free includes your local time zone and one additional favorite. Longitude° Pro is a one-time purchase that unlocks unlimited saved time zones and custom labels.

Calendar capabilities vary by provider. Provider-managed reservations may be read-only to protect the source data.
