Usage

meetingtime --from ZONE --date YYYYMMDD --time HHMM [--to ZONE [ZONE ...]]
       [--profile NAME] [--exclude ZONE [ZONE ...]]
       [--format TEMPLATE] [--date-format STRFTIME] [--time-format STRFTIME]
       [--separator SEP] [--config PATH]

• --from — source time zone. Accepts an IANA name (America/Toronto) or a friendly city alias (Toronto). See src/meetingtime/aliases.py for the full list.
• --date — source date as YYYYMMDD, e.g. 20260710.
• --time — source time as 24-hour HHMM, e.g. 0900.
• --to — one or more target zones/cities. If --profile is given, these are added on top of the profile's zones. If omitted with no profile, falls back to the timezones list in your config file, or just the source zone.
• --profile — use a named [profiles.NAME] section from the config file as the base zone list.
• --exclude — zones/cities to remove from the final output. Takes precedence over all other zone sources including --to and --profile.
• --format — a format name defined in [format], a literal template string using {city} {date} {time} {abbr} {tz} placeholders, or the special value markdown for a table. Default: '{city} ({date}, {time} {abbr})'.
• --date-format — strftime pattern for the {date} field. Default: %b %-d (e.g. Jul 10). Example: --date-format '%Y-%m-%d' → 2026-07-10. Can also be set via date_format in the config file.
• --time-format — strftime pattern for the {time} field. Default: %H:%M (e.g. 14:00). Example: --time-format '%I:%M %p' → 02:00 PM. Can also be set via time_format in the config file.
• --separator — string used to join entries (default '; ').
• --config — path to a TOML config file (default ~/.config/meetingtime/config.toml).

Config file

Avoid retyping your team's zones every time by creating ~/.config/meetingtime/config.toml:

date_format = '%Y-%m-%d'
time_format = '%I:%M %p'

[format]
short   = '{city} {time} {abbr}'
compact = '{city} ({time})'

[profiles.work]
timezones = ['America/Toronto', 'Europe/London', 'Asia/Tokyo']
format = 'short'

[profiles.asia]
timezones = ['Asia/Singapore', 'Asia/Hong_Kong', 'Asia/Tokyo']

See examples/config.toml for a more complete example.

Then run with a profile:

meetingtime --from Toronto --date 20260710 --time 0900 --profile work

Add extra zones on top of the profile:

meetingtime --from Toronto --date 20260710 --time 0900 --profile work --to Singapore

Exclude a zone from the output:

meetingtime --from Toronto --date 20260710 --time 0900 --profile work --exclude Tokyo

Markdown table output
